JAVA中怎么执行带参数的外部命令？(例如del d:\abc.txt)

Question

在java.lang.runtime包里有方法：exec()可以用来调用外部命令

Answer 1

              try
              {
                Process run = Runtime.getRuntime().exec("del d:\abc.txt");
                run.waitFor(); //等待直到该进程运行结束
              }
              catch(Exception e)
              {
                e.printStackTrace();
              }
            }

Answer 2

Process run = Runtime.getRuntime().exec("del d:\\abc.txt");
or
Process run = Runtime.getRuntime().exec("del d:/abc.txt");

Answer 3

给你,请参考:
Runtime r=Runtime.getRuntime(); 
Process p=null; 
try{ 
   p=r.exec("cmd  /q  /c del d:\abc.txt"); 
} catch(Exception e){ 
  System.out.println(e.toString());
}
