Introduction to JAVA


Java is a high-level programming language. It is an object-oriented programming language, developed by James Gosling, Patrick Naughton, and other developers at Sun Microsystems. Program written in java run on every Operating System such as Windows, Mac OS, and the various versions of UNIX. without any modification. Java has its own virtual machine called Java Virtual machine (JVM). It is one of the most popular and secure programming languages. Nowadays based on the importance of web and mobile applications, Java is considered to be very useful for software enterprises. It is used widely and consistently in the speed of the development of software systems. especially if you are unaware of the know-hows of JAVA. We are here to help

you out in these situations.

System Requirement

  • Windows xp/7/8 or Linux operating system
  • Java JDK
  • Notepad or any other editor

Features of JAVA by JAVA Programming Assignment Help Experts


Java is designed to solve the problems encountered in modern programming. It is simple, portable, reliable, and interactive.

Portable and Independent

Java has portability due to its compiler that generates bytecode that can be executed on any machine by interpreter JVM.

Java is Independent that can be easily executed from one machine to another without modification of the program.

Robust and Secure

Java is a strong type of language which makes java Robust. In JAVA, Bugs, Error are very rare. JAVA Compiler checks whether there is an error during compile-time or not and Interpreter checks for runtime error that makes the software secure from the crash.

High Performance

Java performs program execution very impressive because of the bytecodes. Multithreading, Memory Consumption, Runtime of program in java also plays a role in high performance. It is built to reduce overhead.

Ease of Development

Java is easy to use as programming languages. It helps programmers in reducing overhead by reusable code to the compiler and it is easy to handle bugs. It is easy to understand during the development.

Example of JAVA Programming Assignment Help By Assignment Hippo


An introductory “Hello World” program in JAVA looks like

	// Your First Program

	class Main{

	public static void main(String[] args) {

	System.out.println("Hello, World!");

				}

		}

Advantage of JAVA


Object-Oriented Concept

Java is class-based programming languages that follow object-oriented programming concepts. Object is an instance of a class, it can be functions, variables, or any data structures. It is easily reused in other programs. It makes our programs organized and Clear. For making decisions during the design of Software systems, A good understanding of OOPS concepts helps. OOPS consists of concepts like Inheritance, Abstraction, Encapsulation, and Polymorphism.

Platform independent

Java is Platform independent languages which means compiled code of java (bytecode) run on every operating system. The output of the compiler is a .class file (bytecode). This generated bytecode needs an interpreter to execute it on a machine. Java has JVM as an interpreter that executes the bytecode.

Portable

Java has Portability due to Platform independent, Converting a java source code into its bytecode which makes it easier to run on any environment. The only need is JVM installed on each platform.

Secure

Java is the most secure programming language. We can build more secure software systems with java due to No explicit pointer. It has a default safeguards using access specifier that allows access to classes.

Multithreaded

Java has a feature of Multithreading. Multithreading means concurrent execution of two or more blocks of a program. Each block of a program is known as a thread. So thread is a light-weight process. Each and every thread has a priority, higher priority threads executed first than lower priority. This is basically used to maximize the utilization of CPU to get maximum throughput. Java interpreter JVM allows threads for concurrent execution.

Disadvantage of JAVA

Memory

Java runs on a JVM interpreter, So it consumes more memory than other programming languages. It also has no control for garbage collection that provides functions like free(), delete() to reduce memory overhead.

Cost

JAVA JVM allows the programs run to be platform-independent. JVM compiles the program once and runs it on a different machine. So it is costly due to JVM as it requires higher memory and hardware

Low-level programming

Java has no support of low-level programming such as pointer is missing. Instead of pointer JAVA have references much closer to the pointer. References cannot be manipulated, but Pointer can.

Conclusion

JAVA like every language has its own set of merits and demerits. Despite this, you cannot disregard its prowess in areas of software development and object-oriented programming concepts. It provides the ease of syntax and control and also providing portability, compatibility, and support for legacy systems in the modern world.

Java Assignment Sample Solved by Experts


1. Create a word index of each file and store that index into an output file. If your
	input file is called a.txt , then your output file must be called a_output.txt and
	your output will be stored in the output folder that was specified. You will create
	an output file for each input file. Your word index should be created in the
	following way:

a. Read in all words. A word is any consecutive sequence of letters,
	numbers, apostrophes, special symbols, etc. The only things that delimit
	words are a space, tab and newline (i.e. whitespace). In my sample files, I
	am using the default delimiters specified by the Scanner class. If you use
	something different, you may get different results. You should store the
	words into one of the following Collections: TreeSet, HashSet, TreeMap or
	HashMap. If you don’t, your code will likely run very slow. All words are
	case insensitive. For example, the words cat , Cat , CAT and cAT are all
	considered the same word. Punctuation and other symbols are not to be
	filtered out. Therefore, cat: and cat are two separate words (note the
	colon after the first cat).

b. Along with reading in all of the words, remember which “page” the word
	was on. We will start counting from page 1.
	c. For each file, after you have read in all of the words, you should write out
	your word index to that files output file. You should write out each word
	that appears in the file and for each word that you write out, you must also
	write what page(s) that word appears on. You must write out the words in
	alphabetical order and only put 1 word per line. Assume the word cat
	appears on pages 4, 10 and 16, your output should be formatted in the
	following fashion:
	cat 4, 10, 16
	In other words, it is the word, followed by a space, followed by the page(s)
	that word appeared on where each page is separated by a comma (see
	sample input/output). Page numbers must appear in ascending order.
	Words that appear multiple times on the same page should not show up
	multiple times in the final output. For example, if the word cat appears on
	page 4 a total of 3 times, page 4 should only show up once in the output.

2. You must solve this project in 3 different ways:

a. (22 pts) The first way is without using threads. You must call your file that
	does not use threads Index.java . You must time your code and determine
	how long it took to solve without using threads. Your program will create
	the appropriate files and then print out 1 thing to the terminal window: the
	amount of time it took to execute in milliseconds.

b. (44 pts) Once you have your solution to 4a, modify it so that it uses
	threads in some fashion. The most natural way to use threads is to create
	a new thread for each file you read in. If you are testing this on a machine
	with multiple cores, you should notice a significant decrease in time
	(assuming you are using large enough files). You must call your file that
	uses threads IndexRunner.java . Note that this is not saying you are only
	allowed to create 1 file. Your main method must be in IndexRunner.java
	but you can create as many files as you want. Your program will create
	the appropriate files and then print out 1 thing to the terminal window: the
	amount of time it took to execute in milliseconds. Be sure to wait for your
	threads to finish before reporting a time.

c. (44 pts) In short, you are creating a global word index. This differs from
	the previous question in that you need to send your results back to the
	master thread so that the master thread can produce the output. Only the
	master thread is allowed to produce any output for this part. You
	must name this master file GlobalRunner.java . You can create more than

1 Java file. Your main method must be in GlobalRunner.java but you can
	create as many Java files as you want.
	
	Create a word index for each file and store each index into a single output
	file called output.txt that is stored in the specified output folder. The
	output will be a comma separated file. The first line of your output file must
	be this heading:
	Word, first.txt, second.txt, third.txt, xfourth.txt, etc.
	In other words, the first word should be Word. This is followed by the
	names of the input files in alphabetical order.
	Your outputs will be combined. The words will be case insensitive and will
	appear in alphabetical order. For example, assume the word cat is in a.txt
	on pages 2, 4, 6, is in b.txt on 3, 5, 7 and is in c.txt on 2, 5, 7. Your output
	line for cat would be:
	cat, 2:4:6, 3:5:7, 2:5:7
	Since commas are used to delimit the files, colons will be used to delimit
	page numbers. If the word dog is in a.txt on pages 2 and 5, is not in b.txt
	but is in c.txt on page 8, then your output line for dog would be:
	dog, 2:5, , 8
	You are welcome to use whatever callback or synchronization solution you
	want but you have to make sure that only the master thread creates the
	output. No worker thread is allowed to print anything. Your program will
	create the appropriate output file and then print out 1 thing to the terminal
	window: the amount of time it took to execute in milliseconds.
