Java如何重命名檔？

在java編程中，如何重命名檔？

此示例演示如何使用File類的oldName.rename To(new_Name)方法重命名檔。

package com.zaixian;

import java.io.File;

public class RenameFile {
    public static void main(String[] args) {
        File oldName = new File("F:/worksp/javaexamples/java_files/demo1.txt");
        File newName = new File("F:/worksp/javaexamples/java_files/demo1-new.txt");

        if (oldName.renameTo(newName)) {
            System.out.println("renamed");
        } else {
            System.out.println("Error");
        }
    }
}

執行上述示例代碼，將產生以下結果 -

renamed

示例-2

以下是java中重命名檔的另一個示例：

package com.zaixian;

import java.io.File;

public class RenameFile2 {
    public static void main(String[] args) {
        File oldfile = new File("F:/worksp/javaexamples/java_files/oldfile_name.txt");
        File newfile = new File("F:/worksp/javaexamples/java_files/newfile_name.txt");

        if (oldfile.renameTo(newfile)) {
            System.out.println("File name changed succesful");
        } else {
            System.out.println("Rename failed");
        }
    }
}

執行上述示例代碼，將產生以下結果 -

File name changed succesful
