Singleton instantiation

Question

Below show is the creation on the singleton object.

public class Map_en_US extends mapTree {

    private static Map_en_US m_instance;

    private Map_en_US         


        

Answer 1

The static block is executed when the class is first loaded by the JVM. As Bruno said, that helps with thread safety because there isn't a possibility that two threads will fight over the same getInstance() call for the first time.
