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 Assignment Help Experts and Developer


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, Errors are very rare. JAVA Compiler checks whether there is an error during compile-time or not and the 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 the 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 the programming language. 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.

Advantage of JAVA Explained by JAVA Programming Assignment Help Experts


  • Object-Oriented Concept: Java is the class-based programming language that follows object-oriented programming concepts. The 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 a Platform independent language which means compiled code of java (bytecode) runs 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 independence, Converting a java source code into its bytecode 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 default safeguards using an 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 the thread is a lightweight process. Each and every thread has a priority, higher priority threads are executed first than a lower priority. This is basically used to maximize the utilization of the CPU to get maximum throughput. Java interpreter JVM allows threads for concurrent execution.

Disadvantage of JAVA while using JAVA Programming Assignment Help from Experts


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 a pointer JAVA have references much closer to the pointer. References cannot be manipulated, but Pointer can.

Conclusion of Java Programming

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 Help Sample Solved by Our JAVA 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`}
