哪里错了啊

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);

  这哪里错了啊

    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+=one==>"+three);
         three-=one;
         System.out.println("three-=one==>"+three);
        three*=one;
         System.out.println("three*=one==>"+three);
        three/=one;
         System.out.println("three/=one==>"+three);
        three%=one;
       System.out.println("three%=one==>"+three);
    }
}

    除了第一个three前要加int以外其他的three都不用加int，否则会造成重定义的错误
