Files.move

test.txtをtest dirに移動するプログラム
移動先は...testではなく...test\test.txtを指定する

public class SampleProject {
    public static void main(String[] args) throws Exception{
        Path p1 = Paths.get("c:\\dirtest");
        File f = p1.toFile();
        method2(f);
        Path p2 = Paths.get("c:\\dirtest\\test.txt");
        Path p3 = Paths.get("c:\\dirtest\\test\\test.txt");
        Files.move(p2,p3);
        method2(f);
    }
    static void method2(File pf) {
        System.out.println("----------------");
        method(pf,"",null);
    }
    static void method(File pf, String indent, FileFilter ff) {
        class SampleClass {
            File[]  method() {
                if(ff == null) return pf.listFiles();
                else  return pf.listFiles(ff);
            }
        }
        File[] fs = new SampleClass().method();
        for(File f:fs) {
            System.out.print(indent + f.getName());
            if(f.isDirectory())  System.out.println("   is directory.");
            else  System.out.println("    is file");
            if(f.isDirectory())  method(f, indent + " ",ff);
        }
    }
}
