我有以下一个java文件：
package javatest1;

import java.util.ArrayList;
import java.util.List;

public class javatest1 extends common{

    /**   
     * @param
     * @param args
     */   
    public static  void main(String[] args) {
   
        
        int[] arr={33,25,55,45,12};
        printarray(arr);
        
        
    }
   
   
            
}
以下是common类内容:
package javatest1;

import java.util.ArrayList;


import java.util.List;


class swapobj
{
    E swapvalue;
}

public class common {
   
    //简单打印
    public static  void print(E value)
    {
        System.out.println(value);
    }

    //字符串每个字符变成ascii码
    public static StringBuilder stringchangeasc(String value)
    {
         char[] ca;
         int cai;
         StringBuilder sb=new StringBuilder();
         ca = value.toCharArray(); //把传过来的value转换为字符数组           
         for(int i=0;i E argmax(E... arg){
           E max = arg[0];
           int len=arg.length;
           for(int i=1;i void printarray(E[] arr)
     {
         E[] arr={33,25,55,45,12};
         for(int i=0;i
