//赋值运算符 
        /*int a = 0;
        a = 2;
        System.out.println("a=0"+"="+".."+a);
        int b = 0;
        b+=2;
        System.out.println("b=0"+"b+=2"+".."+b);
        int c = 0;
        c-=2;
        System.out.println("c=0"+"c-=2"+".."+c);
        int d = 1;
        d*=2;
        System.out.println("d=1"+"d*=2"+".."+d);
        int e = 2;
        e/=2;
        System.out.println("e=2"+"e/=2"+".."+e);
        int f = 2;
        f%=2;
        System.out.println("f=2"+"f%=2"+".."+f);int a = 0;
