getPath vs getAbsolutePath vs getCanonicalPath
getPath
以构造路径作为返回值
getAbsolutePath
以绝对路径作为返回值
getCanonicalPath
以绝对路径作为返回值(如果路径包含.或..会进行处理)
public static void main(String[] args){
File file1 = new File(".\\xxx.txt");
File file2 = new File("D:\\aaa\\xxx.txt");
System.out.println(file1.getPath());
System.out.println(file1.getAbsolutePath());
System.out.println(file1.getCanonicalPath());
System.out.println("------------------------");
System.out.println(file2.getPath());
System.out.println(file2.getAbsolutePath());
System.out.println(file2.getCanonicalPath());
}
输出如下内容:
.\xxx.txt
D:\aaa\.\xxx.txt
D:\aaa\xxx.txt
------------------------
D:\aaa\xxx.txt
D:\aaa\xxx.txt
D:\aaa\xxx.txt
