How Can I restrict an integer input value?

Question

Alright, I am making a HiLo game and I found an issue with the code. The player starts with 1000 points but they can place a bet higher than the number of points they have. I want it so they can not bet more than what they have

int playerPoints = 1000;
int betPoints;
int predict;
int randomNumber;

System.out.println("Enter the points you want to risk");
betPoints = input.nextInt();

I need betPoints to be less than or equal to playerPoints. How can I restrict the integer to obey that?

Place the input collection into a loop (like a while loop), add an if statement to check for validity, and then display an error and recollect if necessary. BTW, you also need to ensure they do not enter, presumably <=0. — KevinO

With Math.min() for example :

betPoints = Math.min(playerPoints, betPoints);

change betPoints = input.nextInt(); with,

do {
    betPoints = input.nextInt();
} while(betPoints > playerPoints);
