哪里錯(cuò)了啊

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);

? 這哪里錯(cuò)了啊

}

除了第一個(gè)three前要加int以外其他的three都不用加int，否則會造成重定義的錯(cuò)誤
