What are a few ways you can improve the memory footprint of a Java application?

Here are three key steps you can take to improve the memory footprint:

• Limiting the scope of local variables. Each time the top scope from the stack is popped up, the references from that scope are lost, and this could make objects eligible for garbage collection.
• Explicitly set variable references to null when not needed. This will make objects eligible for garbage collection.
• Avoid finalizers. They slow down program performance and do not guarantee anything.
