main和setVisible不工作的Java登录

我尝试了这段代码，在一个文本文件中，我需要4个登录用户名和密码，但当我尝试main时，setVisible不起作用。NetBeans说，找到setVisible符号，当我删除以运行时，它只生成，没有弹出任何内容。这段代码希望有人能帮助我谢谢

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner; // I use scanner because it's command line.

public class Identification {

     public void run() throws FileNotFoundException {
        Scanner scan = new Scanner(new File("C:\\Program Files (x86)\\TP3\\Accessinit.txt"));
        Scanner keyboard = new Scanner(System.in);
        String user = scan.nextLine();
        String pass = scan.nextLine(); // looks at selected file in scan
        String inpUser = keyboard.nextLine();
        String inpPass = keyboard.nextLine(); // gets input from user
        if (inpUser.equals(user) && inpPass.equals(pass)) {
            System.out.print("login");
        } else {
            System.out.print("error");
        }
    }

    public static void main(String[] args) {
        Identification idento = new Identification();
        idento.setVisible(true);
    }
}

我看不到标识类中定义了visible变量或setVisible方法，因此无法调用它。如果这适合你，你可以试试这样的

public class Identification {
    private boolean visible;

    public void setVisible(boolean visible) {
         this.visible = visible;
    }

public void run() throws FileNotFoundException {
    Scanner scan = new Scanner(new File("C:\\Program Files (x86)\\TP3\\Access\\init.txt"));
    Scanner keyboard = new Scanner(System.in);
    String user = scan.nextLine();
    String pass = scan.nextLine(); // looks at selected file in scan

    String inpUser = keyboard.nextLine();
    String inpPass = keyboard.nextLine(); // gets input from user

    if (inpUser.equals(user) && inpPass.equals(pass)) {
        System.out.print("login");
    } else {
        System.out.print("error");
    }

}
