public class InitTest {
public static int VALUE = 100;

static
{
System.out.println("VALUE1 = " + VALUE);
VALUE += 200;
System.out.println("VALUE2 = " + VALUE);
}

public InitTest() {
System.out.println("VALUE3 = " + VALUE);
VALUE += 300;
System.out.println("VALUE4 = " + VALUE);
}

public static void main(String args[]) {
new InitTest();
new InitTest();
}
}
Output:
