錯在哪，==》是神莫意思，為甚莫要("three=one+two==>"+three);
public class HelloWorld{
? ? public static void main(String[] args) {
? ?int one = 10 ;
? ? ? ? int two = 20 ;
? ? ? ? int three = 0 ;
? ? ? ??
? ? ? ? int three=one+two;
? ? ? ? System.out.println("three=one+two==》+"three);
? ? ? ? int three+=one;
? ? ? ? System.out.println("three+=one==》 +"three);
? ? ? ? int three-=one;
? ? ? ? System.out.println("three-=one==》 +"three);
? ? ? ? int three*=one;
? ? ? ? System.out.println("three*=one==》 +"three);
? ? ? ? int three/=one;
? ? ? ? System.out.println("three/=one==》 +"three);
? ? ? ? int three%=one;
? ? ? ? System.out.println("three%=one==》 +"three);
? ? ? ??

==》是為了輸出語句好看，像一個箭頭指向結果，你也可以直接只要輸出結果System.out.println(three);
