? three -= one; （此處three=40，上一步得到的）? //three-=one ==40-10=30
? ? ? ? System.out.println(three);? //30
? ? ? ? three *= one;? ? //300
? ? ? ? System.out.println(three);
? ? ? ? three /= one;? //30
? ? ? ? System.out.println(three);
? ? ? ? three %= one;
? ? ? ? System.out.println(three);? 0

?int one = 10 ;
? ? ? ? int two = 20 ;
? ? ? ? int three = 0 ;
? ??
? ? ? ? three = one+two; = 30
? ? ? ? three += one;? =40
? ? ? ? System.out.println(three);??
? ? ? ? three -= one; （此處three=40，上一步得到的）
? ? ? ? System.out.println(three);
? ? ? ? three *= one;
? ? ? ? System.out.println(three);
? ? ? ? three /= one;
? ? ? ? System.out.println(three);
? ? ? ? three %= one;
? ? ? ? System.out.println(three);
?別忘了，three的值一直在變化
