关于java中继承Arrays类

package com.tarena;
import java.util.Arrays;

public class wang extends Arrays
{    public static void main(String[] args)
    {
        System.out.print("haha");
        wang w=new wang();
        System.out.println(w.f());
        int aa[]={1,3,4,5};
        System.out.println(Arrays.toString(aa));
        
        
    }
    public static char[] f()
    {
        //int a=1;
        char[]b=new char[3];
        b[0]='1';b[1]='1';b[2]='4';
        return b;
        
    }
}
