Question

I have the following method

    public static int modeChooser(){
    int choice = 0;
    Scanner kb = new Scanner(System.in);
    while(choice == 0){
        try {
        choice = kb.nextInt();  
        } catch (Exception e) {
            continue;
        }
        if(choice < 1 || choice > 5){
            continue;
        }
    }

    return choice;
}

The goal is to only allow the user to put in 1,2,3,4, or 5;
If the user types a string or a too high/low number, the method should just restart until i have the proper int.

Here is an example for the flow:

User types: 1 -> all ok
User types: saddj -> method restarts -> user types 3 –> all ok

Any ideas?

Answer 1

Change to:

do {

    // read choice value

    if (choice < 1 || choice > 5) {
        // hint to user
    }

} while(choice < 1 || choice > 5);
