Java编程思想：File类其他方法

import java.io.File;

public class Test {
    public static void main(String[] args) {

        MakeDirectories.test();
    }
}

class MakeDirectories {

    //用于展示File对象各种信息
    private static void fileData(File file) {
        StringBuilder sb = new StringBuilder();
        sb.append("\nAbsolute path:"+ file.getAbsolutePath());
        sb.append("\n     Can Read:"+ file.canRead());
        sb.append("\n    Can Write:"+ file.canWrite());
        sb.append("\n     Get Name:"+ file.getName());
        sb.append("\n   Get Parent:"+ file.getParent());
        sb.append("\n     Get Path:"+ file.getPath());
        sb.append("\n       Length:"+ file.length());
        sb.append("\n LastModified:"+ file.lastModified());
        sb.append("\n      Is File:"+ file.isFile());
        sb.append("\n Is Directory:"+ file.isDirectory());
        System.out.println(sb.toString());
    }

    //用于测试rename方法
    private static void rename(String file1,String file2) {

        File o = new File(file1);
        File n = new File(file2);

        o.renameTo(n);
    }

    //
    private static void deleteandmkdirs(String file) {
        File f = new File(file);

        //文件存在，则删除
        if (f.exists()) {
            f.delete();
        }

        //文件不存在，则创建
        else {
            f.mkdirs();
        }
    }

    public static void test() {

        //File f = new File(".");
        //fileData(f);

//        String file1="./file1";
//        String file2="./file2";
//        //File f1 = new File(file1);
//        //File f2 = new File(file2);
//        rename(file1,file2);
//        File f1 = new File(file1);
//        File f2 = new File(file2);
//        fileData(f1);
//        fileData(f2);

    }
