I've been trying to figure this out for hours but I can't for some reason my output just shows "Sorry that number is too high" and "Sorry that number is too low" at the same time without looping or using a single answer.

import java.util.*;



public class RandomNumbers {



    public static void main(String args) {

        Scanner keyboard = new Scanner(System.in);

        Random numGen = new Random();

        int RanNum = numGen.nextInt(20) + 1; 

        System.out.println("Guess what number im thinking of");

        int num ;

        num = keyboard.nextInt();

        if (num == RanNum)

            System.out.println("Good Job");

        else if  (num > RanNum)

            System.out.println("Sorry that number is too high");

        else if (num < RanNum);

        System.out.println("Sorry that number is too low");



    }

}

Semicolon after else if (num < RanNum) is your problem

you misplaced a semicolon at the end of your third if.
You should still get the Good Job message though.

public static void main(String args) 

{

    Scanner keyboard = new Scanner(System.in);

    Random numGen = new Random();

    int RanNum = numGen.nextInt(1) + 1; 

    System.out.println("Guess what number im thinking of");

    int num ;

    num = keyboard.nextInt();

    if (num == RanNum)

        System.out.println("Good Job");

    else if  (num > RanNum)

        System.out.println("Sorry that number is too high");

    else if (num < RanNum)

        System.out.println("Sorry that number is too low");



}

edit: sorry, too late :)

To keep prompting the user use a while loop to check whether they guessed correct or not. I would also recommend adding another input check for exiting without getting it correct. Brief example:

boolean incorrect = true;

while(incorrect) {



  //Code to prompt for input



  if(userIsCorrect || input == -1){

    incorrect = false;

    //Program will exit loop when this is set to false

  }

}
