Introduction
In order to develop java programs Java development kit (JDK) is
needed.
JDK is an open source and can be downloaded from oracle website.
JDK come in various versions the latest version of JDK is JDK 1.10.1
JDK contains some tools which are useful for development of the java
programs

Tools in JDK
Basic tools available in the JDK are
javac :- Java Compiler .
java :- java Interpreter
Javah :- C header and stub generator. Used to write
native methods.
javap :- Class file disassembler
 javadoc :- documentation generator
jdb :- java debugger
jar :- creates java archive files (jar)

Compilation Process
Java program can be written on notepad and should be saved with
.java extension. The programs can be compiled on command
prompt using the following command
>javac FileName.java
If the program is free of errors then java compiler compiles the java
program and generates .class file
The class file contains byte code which is highly encrypted format of
the java program which can be understandable by java interpreter
only
Sample.java javac Sample.class

Interpretation Process
After the generation of the class file we can run the java programs
easily on command prompt with the following command
>java FileName
Even the output of the java program can be routed to a file with the
following command
>java FileName >OutputFileName
Sample.class java Sample.exe

Other ways of developing Java programs
Java programs can also be developed using some tools like
Editors like – Edit plus, notepad++, jEdit, kawapro….
IDE like : -Ecllipse, Nebeans, BlueJ, jGrasp, IntelliJ….
IDE provides some additional features like
error checking
smart typing
Powerful GUI developer
Support for various versions of JDK
Debugging tools
Non-Java code Support
The most popular IDEs are Eclipse and Net beans both are open
source can e downloaded from internet.
