 2     private static int b = 1;
 3     private int a = 1;

 5     public static void main(String[] args) {
 6         StaticTest a1 = new StaticTest();
 7         StaticTest a2 = new StaticTest();
 8         a1.a = a1.a+1;
 9         a2.a = a2.a+1;
10         System.out.println("a1.a="+a1.a);
11         System.out.println("a2.a="+a2.a);

13         StaticTest b1 = new StaticTest();
14         StaticTest b2 = new StaticTest();
15         b1.b = b1.b+1;
16         b2.b = b2.b+1;
17         System.out.println("b1.b="+b1.b);
