实现叫简单但是很经典的新闻发布管理系统

package news;
import java.util.*;
public class StrEncode {
  public StrEncode(){}

    byte[] temp;
    String newstr="";
    try{

    }
    catch(Exception e){
      System.out.print(e.toString());
    }
    return newstr;
  }
  public String HtmlRep(String str){
    String nstr=this.strReplace("\n","<BR>",str);
    return nstr;
  }
