  2. Text in a program that the compiler ignores

  3. A place to store information in a program


What is the process of fixing errors called?

  1. Defrosting

  2. Debugging

  3. Decomposing



b. Compiling a program converts a .java file into a .class file or a set of .class files.


c. Variables are one place to store information; later you'll learn about others such as arrays and constants. Weebles wobble but they don't fall down, and comments are text in a program that the compiler ignores.
