Java实现Windows下结束系统进程

import java.io.Console;
import java.io.IOException;

public class KillProcess
{
    private static final String X = " /PID ";

    private static final String TSKILL_CMD = "taskkill";

    public static void main(String[] args) throws IOException
    {
        System.out.println("Please input pid:");
        Console console = System.console();
        if (null != console)
        {
            int pid = Integer.valueOf(System.console().readLine());
            try
            {
                Runtime.getRuntime().exec(TSKILL_CMD + X + pid);
            }
            catch (IOException e)
            {
                e.printStackTrace();
            }
        }
        else
        {
            System.out.println("");
        }
        System.in.read();
    }

}
