使用扫描仪重命名文件

Question

我需要稍后在我的代码中重命名文件temp.txt。我尝试使用newFile = new File(name);行执行此操作，但这只是完全创建了一个新文件。你能指点我在正确的方向吗？

public static File InputOutput (Scanner console, int in_Out) throws
        FileNotFoundException {
    //<editor-fold>
    String name = "newName";
    String line = "";
    String in_OutText = "";
    File newFile = new File("temp.txt");
    for (int i = 0; i <= in_Out; i++) {
        if (i == 0) {
            in_OutText = "Input";
        } else {
            in_OutText = "Output";
        }
        System.out.print(in_OutText + " file name: ");
        name = console.next();
        if (i == 1) {
            newFile = new File(name);
        }
    }
    PrintStream inputCopy = new PrintStream(newFile)
    Scanner input = new Scanner(name);
    while (input.hasNextLine()) {
        line = input.nextLine();
        inputCopy.println(line);
        inputCopy.println("WORKED");
    }
    return newFile;
}

谢谢！
