{
    static int x1=4;
    int x2=5;
    public static void main( String  args[ ] )
    {
        ex3_3_1 obj1=new ex3_3_1();
        ex3_3_1 obj2=new ex3_3_1();
        obj1.x1=obj1.x1+2;
        obj1.x2=obj1.x2+4;
        obj2.x1=obj2.x1+1;
        obj2.x2=obj2.x2+6;
        x1=x1+3;
        System.out.println("obj1.x1="+obj1.x1);
        System.out.println("obj1.x2="+obj1.x2);
        System.out.println("obj2.x2="+obj2.x2);
        System.out.println("ex3_3_1.x1="+ex3_3_1.x1);
    }
