通过路径获取信息的几种方式

//定义路径
Path path = Paths.get("E:/cn/icer/webservice/client/Business.java");

//获取文件名
System.out.println("The file/directory indicated by path: " + path.getFileName());

//获取根路径
System.out.println("Root of this path : " + path.getRoot());

//获取父目录
System.out.println("Parent : " + path.getParent());

//获取路径元素个数
System.out.println("Number of name elements in path : " + path.getNameCount());

//获取路径 各个元素的名称
for(int i = 0; i < path.getNameCount(); i++) {
System.out.println("Name element " + i + " is : " + path.getName(i));
}

//获取子路径
System.out.println("Subpath(0, 3) : " + path.subpath(0, 3));
