Optimization Of Java

Reduce number of object creations

• memory allocation from heap, which may cause garbage collection when free space is insufficient
• using meta-data to create the virtual table (larger in Java than, for example, C++, as Java methods are virtual by default)
• calling constructors

Eliminate simple methods such as accessor method

Myths

• final modifer with methods or classes reduces the overhead of call of methods - Because the Java compiler cannot know which class will be loaded at runtime, it cannot in-line-expand the methods regardless if they have final or not.
