    Question Need Help With Code for Kitchen Timer

    I have a problem. I tried debugging and I saw nothing pop up. Something is wrong but I cant seem to find it since its not a syntax error. I rechecked everything and I still couldnt find the problem.

    Here is what the code is supposed to do.
    1) Take in the user's integer value.
    2) Print the values as they count with 1 second interval.
    3) When it reaches one a message pops up and says "Time's up!!".

    However when i run it, it asks for input and pops up the message immediately. There is no printing of the countdown, nor is there any one second interval. I have two classes, the main class and a class with all the functions. They names will help you tell what they do from the start.

    Here is the class with the functions.

    package kitchentimer;
    import java.util.Scanner;
    import javax.swing.JOptionPane;



    public class Timer {
    boolean decide=false;
    Scanner input = new Scanner(System.in);

    public void getTime(int t){
    System.out.println("Set the timer value in seconds");
    t=input.nextInt();


    }

    public void runTimer (int tmrValue){
    System.out.println("The timer has started");
    tmrValue++;

    for (int x=1; x<tmrValue{

    System.out.println(tmrValue);
    Thread.sleep(1000);
    tmrValue-=1;

    }

    if(tmrValue==1){
    decide=true;
    }

    }
    public void timerEnd (){
    if (decide==true){
    JOptionPane.showMessageDialog(null,"Time is up!!");
    }

    }

    }




    Here is the main class


    package kitchentimer;


    public class KitchenTimer {

    public static void main(String[] args) {
    int TimeValue=0;
    Timer TimerObject = new Timer();
    TimerObject.getTime(TimeValue);
    TimerObject.runTimer(TimeValue);
    TimerObject.timerEnd();

    }
    }

    Please help me find the problem so I can avoid it in the future.Timer.zipTimer.zip

            public void getTime(int t) {
    		System.out.println("Set the timer value in seconds");
    		t = input.nextInt();
     
    	}
    That method does exactly nothing. You never use t.

    Thanks for the reply. I probably wasn't thinking straight this morning. Ill check it out.

    t was used to store the input value. I don't get what you're saying, please explain.

    --- Update ---

    I have removed all the variables and used a private variable. The problem was that my variable from the input method was not returned to the runTimer method so the local variable was equal to 0 and the code in that class was skipped altogether. When I used the single class variable in all the methods the value input was returned to the other methods. Thank you.
