Java While Loop Question

Hey, Java noob here. your num1 will always be the first value you enter since it's outside of your while loop. i don't know why it happens but when you enter a negative number, your first

if (num1 > num){
    largest = num1;
}

if (num1 > num){
    largest = num1;
}

is accessed and largest is set to the initial num1 value.

public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner stdin = new Scanner(System.in);
        

        int largest = Integer.MIN_VALUE;
        boolean running = true;
        
        
        while(running) {
            System.out.println("Please provide an integer: ");
            int num = stdin.nextInt();
            
            if(num<0) {
                running = false;
                System.out.println("The largest number is " + largest);
                stdin.close();
            }else if(num > largest) {
                largest = num;
            }
        }
    }

public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner stdin = new Scanner(System.in);
        

        int largest = Integer.MIN_VALUE;
        boolean running = true;
        
        
        while(running) {
            System.out.println("Please provide an integer: ");
            int num = stdin.nextInt();
            
            if(num<0) {
                running = false;
                System.out.println("The largest number is " + largest);
                stdin.close();
            }else if(num > largest) {
                largest = num;
            }
        }
    }

i don't know what your homework/quiz is asking you to do but for this problem you pretty much only need onle else if()
