Java static Block __java

The static clause of a class executes when the class is first loaded.

public class TestClass {

	/**
	 * @param args
	 *
	/public static void main (string[] args) throws Exception {
 new Test1 ();
		New Test1 ();
		Class.forName ("Lmiky.test.clazz.Test1");
		New Test2 ();
		New Test2 ();
		New Test3 ();
		New Test3 ();
	}

Class Test1 {
	static {
		System.out.println ("test1");
	}

Class Test2 {
	static {
		System.out.println ("test2");
	}

Class Test3 {
	static {
		System.out.println ("test3");
	}

The result of the execution is

Test1
test2
test3

Indicates that the static block is executed only on the first load.
