这是结果
three = one + two ==> 30
three += one ==> 40
three -= one ==> 30
three *= one ==> 300
three /= one ==> 300
three %= one ==> 0
System.out.println("three *= one ==> "+(three*=one)); //three=300
three*=one; //three=3000
three /= one; //three=300
System.out.println("three /= one ==> "+ three );虽然没看懂这是要干嘛，不过代码跟结果显示的一样。
