Java Developer Kit (JDK)

JDK contains the basic tools and libraries required for Java program development. The tools available in JDK are:

javac – the Java compiler that compiles source codes to byte codes.
java – the Java interpreter that interprets the byte codes to execute.
javadoc – the Java documentation generator in the HTML format from the source code
jdb – the java debugger helps us to locate and fix bugs
javap –a disassembler that displays the accessible functions and data in a compiled class file. It helps in getting the information of a class.
javah – creates C header files that can be used in C programs or make C routines that can be called by Java programs. This allows C and Java program interactivity.
appletviewer – a java interpreter that executes Java applets, used for debugging java applets during development
