请问这里面是怎么计算
int one = 10 ;
int two = 20 ;
int three = 0 ;
three+=one;
System.out.println("thrree+= ==> "+three);
为什么得出的结果是40,不应该是10吗?

public class HelloWorld{
public static void main(String[] args) {
int one = 10 ;
int two = 20 ;
int three = 0 ;
three=one+two;
System.out.println("three=one+two ==> "+three);
three+=one;
System.out.println("three+= ==> "+three);
three-=one;
System.out.println("three-+"+three);
three*=one;
System.out.println("three*="+three);
three/=one;
System.out.println("three/="+three);
three%=one;
System.out.println("three%="+three);你好，three+=one; 这一句的意思是，three + one 赋值给 three，这里上面已经运行过 three=one+two;
所以到 three+=one; 这一步的时候 three 的值是 30；运行 three+=one; 后相当于 three = 30 + 10；
因此，得到的 three 的值是 40；望楼主采纳！
public class HelloWorld{

int one = 10 ;

int three = 0 ;
three=one+two;
System.out.println("three=one+two ==> "+three); //30
three+=one;
System.out.println("thrree+= ==> "+three); //40
three-=one;
System.out.println("three-+"+three); //30
three*=one;
System.out.println("three*="+three); //300
three/=one;
System.out.println("three/="+three); //30
three%=one;
System.out.println("three%="+three); //0举报
0/150
