File的遍历

public class Demo06File {
    public static void main(String[] args) {
        show01();
        show02();
    }

    private static void show02() {
        //File数组
        File file=new File("F:\\basic\\untitled12\\src\\it\\cast\\day14");
        File[] files = file.listFiles();
        for (File f : files) {
            System.out.println(f);
        }

    }

    private static void show01(){
        File file=new File("F:\\basic\\untitled12\\src\\it\\cast\\day14");
        String[] list = file.list();//list数组
        for (String filename:list){
            System.out.println(filename);
        }
    }
}

结果：

demo01
demo02
demo03
F:\basic\untitled12\src\it\cast\day14\demo01
F:\basic\untitled12\src\it\cast\day14\demo02
F:\basic\untitled12\src\it\cast\day14\demo03
