调用系统命令实现删除文件的操作

public class DSOOperation {
 public static void main(String[] args) {
  Runtime run=Runtime.getRuntime();
  try {
   //cmd /c 下面这句就是删除文件
   run.exec("cmd /c  del D:\\tt.txt");
   
   //控制台显示信息
   Process p=run.exec("cmd /c  dir src");
   InputStream is=p.getInputStream();
   BufferedReader read=new BufferedReader(new InputStreamReader(is));
   while(true){
    String s=read.readLine();
    if(s==null)break;
    System.err.println(s);
   }
  } catch (IOException e) {
   e.printStackTrace();
  }
 }
}
