為啥我一個(gè)一個(gè)輸出老是運(yùn)行失敗
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); 為什么我一個(gè)一個(gè)輸出運(yùn)行失敗了

}
不用增加變量，直接輸出。

要放在一起算? 因?yàn)樗恳淮味歼\(yùn)用了前一次的計(jì)算結(jié)果累計(jì)使用的，一次次的算每一次的數(shù)值都是初始的賦值? 算起來(lái)當(dāng)然不正確。
