How can I add string components to an integer for an if statement?-CodePudding

I am currently making an if statement, but in that if statement I need to add string character, so based on what you say it either takes away 4 or not.

public static void yesornodisability()
{
    String disabled;
    Scanner scanner = new Scanner(System.in);
    System.out.println("Are you registered disabled(Yes / No)? ");
    disabled = scanner.nextLine();
    return;
}

This is the method I am using for my string, When I run the top code (yesornodisability) it works. However when I run the second code it gives me an error saying void cannot be converted to java.lang.String.

This is my if statement

public static int swimmingprice()
 {
     int userAge = age();
     int totalCost = total();
     String disabled = yesornodisability();
        
     if (userAge<=18)
     {
         totalCost= totalCost/2;
     }
     else if(userAge>=65)
     {
         totalCost = totalCost-3;
     }
     else if(disabled.equals("Yes"))
     {
         totalCost = totalCost-4;
     }
     else
     {
         totalCost = 10;
     }
     
     System.out.println("The swimming price for you is " totalCost " pounds.");
     return swimmingprice();
 }

CodePudding user response：

As others have pointed out, you need to change your method's return type and return the value from it.

Here is fixed code for you.

public static String yesornodisability()
{
    String disabled;
    Scanner scanner = new Scanner(System.in);
    System.out.println("Are you registered disabled(Yes / No)? ");
    disabled = scanner.nextLine();
    return disabled;
}

    public static void yesornodisability()
{
    String disabled;
    Scanner scanner = new Scanner(System.in);
    System.out.println("Are you registered disabled(Yes / No)? ");
    disabled = scanner.nextLine();
    return;
}

You need to get rid of the void and return disabled.

return disabled;

You also need to fix your what your returning in the swimmingPrice() method.

return totalCost;

Instead of System.out.println("The swimming price for you is " totalCost " pounds."); return swimmingprice();

Change to return "The swimming price for you is " totalCost "pounds." Then in the main method System.out.println(swimmingPrice());
