java使用用Runtime调用（弹出）IE

import java.io.IOException;


public class NEM {
	
	public static void main(String args[])
	{
		Runtime rt = Runtime.getRuntime();
		try {
			rt.exec("rundll32  url.dll,FileProtocolHandler  " + "http://www.google.cn");
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
	
}
