I do not want to use something like the Scanner class or the BufferedReader class,that's not my purpose. I want to know if the user pressed the UP key, the DOWN key, the LEFT key, or the RIGHT key, what should I use?

    Take a look at [this question](https://stackoverflow.com/questions/18037576/how-do-i-check-if-the-user-is-pressing-a-key) – Alex Sveshnikov Nov 10 '21 at 07:03

    (1-) This question is not clear. What type of input are you asking about? Are you trying to get input in a GUI? Are you trying to get input from the command line? – camickr Nov 10 '21 at 14:37

UP DOWN LEFT and RIGHT as every character in the keyboard have a ASCII code, so you can actually check it out. Normally in Java, instead of checking if a key has been pressed you could use KeyEvents:

public void keyPressed(KeyEvent e){

    int key = e.getKeyCode();   

    switch(key){
       case KeyEvent.VK_RIGHT: System.out.println("The right arrow key is 
       pressed");
       // Other operations
       break;
       case KeyEvent.VK_LEFT: System.out.println("The left arrow key is 
       pressed");
       // Other operations
       break;
       case KeyEvent.VK_UP: System.out.println("The up arrow key is 
       pressed");
       // Other operations
       break;
       case KeyEvent.VK_DOWN: System.out.println("The down arrow key is 
       pressed");
       // Other operations
       break;
    }                                             

}
