Demo:
import java.nio.file.Path; import java.nio.file.Paths; public class PathInfoTest { public static void main(String[] args) { // 创建绝对路径(位置) Path listing = Paths.get("/Users/jinxing/Documents/pathtest"); System.out.println("File Name: " + // 位置(文件)名称 listing.getFileName()); System.out.println("Number of Name Elements in the Path: " + // (位置)路径层级 / 元素数量 listing.getNameCount()); System.out.println("Parent Path: " + // 上级位置 / 上级文件路径 listing.getParent()); System.out.println("Root of Path: " + // 跟位置(路径) listing.getRoot()); System.out.println("Subpath from Root,2 elements deep: " + // 截断路径——从第1个反斜杠开始截取到第3个反斜杠——反斜杠计数从0开始——结果不包含头尾反斜杠 // /Users/jinxing/Documents/pathtest --> jinxing/Documents listing.subpath(1, 3)); } }
Ran As Java Application:
File Name: pathtest Number of Name Elements in the Path: 4 Parent Path: /Users/jinxing/Documents Root of Path: / Subpath from Root,2 elements deep: jinxing/Documents
