關(guān)于int的問題
為什么前面可以用int，后面關(guān)于“three”的計算不能用int？？？？
public class HelloWorld{
? ? public static void main(String[] args) {
? ?int one = 10 ;
? ? ? ? int two = 20 ;
? ? ? ? int three = 30 ;
? ? ? ? three +=three+one;
? ? ? ? three -=three-one;
? ? ? ? three *=three+one;
? ? ? ? three /=three/one;
? ? ? ? three %=three%one;
? ? ? ? System.out.println("three = one+two==>"+three);
? ? ? ? System.out.println("three += one ==>"+three +);
? ? ? ? System.out.println("three -= one ==>"+three -);
? ? ? ? System.out.println("three *= one ==>"+three *);
? ? ? ? System.out.println("three /= one ==>"+three /);
? ? ? ? System.out.println("three %= one ==>"+three %); ??
}
}

System.out.println("three += one ==>"+three +); 有問題吧 three+不是一個變量吧

加運算符？ ?three+ 什么意思
