想不通啊,小弟特此來(lái)求助啊
要輸出three+=one==>40,但為啥（）里面還要+three呢
int?one=10;
int?two=20;
three=one+two
System.out.println("three=one+two==>"+three);
three+=one;
System.out.println("three+=one==>"+three)

System.out.println（這里面的+好是起到連接作用，將后面那個(gè)three值轉(zhuǎn)化為String類和前面的three=one+two==>連接起來(lái)。）這樣你輸出的才會(huì)是three=one+two==>（three的值）
