java打开文件夹

调用系统命令（windows系统）

package cn.test;

import java.io.IOException;

public class Test {
	private static final String FILE_PATH = "c:/";

	public static void main(String [] args) {
		try {  
            String[] cmd = new String[5];  
            cmd[0] = "cmd";  
            cmd[1] = "/c";  
            cmd[2] = "start";  
            cmd[3] = " ";  
            cmd[4] = FILE_PATH;  
            Runtime.getRuntime().exec(cmd);  
        } catch (IOException e) {  
            e.printStackTrace();  
        }  
	}
}

 

直接使用java代码

java.awt.Desktop.getDesktop().open(new File("D:\\test"));
