• Unused package in a program automatically gets deleted.

• Memory occupied by objects with no reference is automatically reclaimed for deletion.

• Java deletes all unused java files on the system.

• The JVM cleans output of Java program.

Java compiled source code programs have extension

• .java

• . source

• .class

• . compile
