我想用Java程序打开QQ之类的应用，麻烦各位指教下。

package shuru;
import *;
import java.util. *;

public class Shuru {
    public static void main(String[] args)throws Exception{
        try {
            Process pro = Runtime.getRuntime().exec("C:\\Users\\Public\\Desktop\\QQ.lnk");
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            
        }

    }

}
