Creating and Running java application programs

The java environment includes a large number of development tools and hundreds of classes and methods. The development tools are part of the system known as java development kit(JDK) and the classes and methods are part of the java standard library(JSL), also known as the application programming interface (API).

          The JDK comes with a number of tool that used to to develop and run your java application programs. They include

  1. appletviewer - for viewing java applets.
  2. javac- java compiler.
  3. java- java interpreter.
  4. javap- java dissembler.
  5. javah- for C header files.
  6. javadoc- for creating HTML documents.
  7. jdb - java debugged.


                  The way these tools are applied to build and run application programs is illustrated below.



To create a java program, we need to create a source code file using a text editor. The source code is then compiled suing the java compile javac and executed using the java interpreter java.

        The java debugger jdb is used to find errors, if any, in the source code. A compiled java program can be converted into source code  with the help of java disassemble " javap".
