這樣就對(duì)了~
public class HelloWorld{
? ? public static void main(String[] args) {
? ?int one = 10 ;
? ? ? ? int two = 20 ;
? ? ? ? int three = 0 ;
? ? ? ? System.out.println(three+=one+two);
? ? ? ? System.out.println(three+=one);
? ? ? ? System.out.println(three-=one);
? ? ? ? System.out.println(three*=one);
? ? ? ? System.out.println(three/=one);
? ? ? ? System.out.println(three%=one);
