import javax.tools.Tool;
import java.net.URLDecoder;//获取类路径
public  final class test132 {public static String getClassPath(){String path=test132.class.getClassLoader().getResource( "" ).getPath().toString();try {return URLDecoder.decode( path,"UTF-8" );}catch (Exception e){e.printStackTrace();}return path;}
}

上面编写方法

 

定义一个实现类

import javax.tools.Tool;
//获取文件程序类的路径
public class test133 {public static void main(String[] args){String classPath=test132.getClassPath();System.out.println( classPath );}
}

运行结果
