如何在java中调用dos命令 100分求解

[shaoang007]

最好给我一个例子 谢谢

比如 String command = "cmd";
execute(command）

public static String execute(String command)
throws IOException, InterruptedException {
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec(command);
runtime.gc();
BufferedReader input = new BufferedReader(new InputStreamReader(process.getInputStream()));
String line = null, result = "";
while ((line = input.readLine()) != null)
result += line + "\r\n";
input.close();
if (result.length() == 0)
return null;
else
return result;
}

Runtime.exec("shutdown -s");
如果运行其它则要加上wait()

import java.io.*;
public class Test3
{
public static void main(String[] args)
{

try {
Process s = Runtime.getRuntime().exec("c:\\windows\\System32\\cmd.exe /c dir");//这个地方改为你自己的windows目录
InputStreamReader ir = new InputStreamReader(s.getInputStream());

LineNumberReader input = new LineNumberReader(ir);

String line;

while ( (line = input.readLine()) != null)
{

System.out.println(line);

}
}
catch (IOException ex)
{
System.out.print(ex.getMessage());
}
}
}
