参考中 int three=0; 都已经给three赋值为0了 怎么下面有three=one+two;
int three = 0 ;
three=one+two;
System.out.println("three = one + two ==> "+three);
three+=one;
System.out.println("three += one ==> "+three);
three-=one;
System.out.println("three -= one ==> "+three);
three*=one;
System.out.println("three *= one ==> "+three);
three/=one;
System.out.println("three /= one ==> "+three);
three%=one;
System.out.println("three %= one ==> "+three);
