Three step process that gives us feedback

1. Edit your program

• Create it by typing text on our keyboard

• Eventually we get a text file (Eg : Helloworld.java)
  1. Compile the program to create an executable file

• Here we use a java compiler so it technically creates a java byte-code file (Eg : Helloworld.class)

• If there is a mistake the compiler tells us so and then we go back to Step 1 and fix things (mainly : Recompile)
  1. Run our program Eg :java Helloworld.java
• There may be errors sometimes in which we must Recompile again
