Java中获取程序路径

package test;

public class getDir {
 public static void main(String[] args) {
  //包路径：E:\Java EE\myeclipse\Test1
  System.out.println(System.getProperty("user.dir"));
  getDir2 gd=new getDir2();
  gd.function();
 }
}
class getDir2{
 void function(){
 //类路径：/E:/Java%20EE/myeclipse/Test1/bin/test/
 System.out.println(this.getClass().getResource("").getPath());
 }
}
