Verified
So I ask users through input through these two methods:
```java
public static String whileLoopInputString (Predicate<String> checkCase, String inputMessage, String errorMessage, Scanner scanner) {
String input = "";
while (!checkCase.test(input)) {
System.out.println(inputMessage);
input = scanner.nextLine();
if (!checkCase.test(input)) {
System.out.println(errorMessage);
}
}
return input;
}
public static byte whileLoopInputByte (Predicate<Byte> checkCase, String inputMessage, String errorMessage, Scanner scanner) {
byte input = -1;
while (!checkCase.test(input)) {
try {
System.out.println(inputMessage);
input = scanner.nextByte();
scanner.nextLine();
if (!checkCase.test(input)) {
System.out.println(errorMessage);
}
} catch (InputMismatchException e) {
System.out.println(errorMessage);
scanner.nextLine();
}
}
return input;
}
```
**I get the scanner bug, mainly when I use the byte, then string input method in that order:**
```java
switch (bytInput) {
case 1:
System.out.println("Rules");
break;
case 2:
strCreatedPlayerName = Logic.whileLoopInputString(
conditions);
break;
case 3:
strUsernameToLoadIn = Logic.whileLoopInputString(conditions);
case 4:
method();
break;
case 5:
bolIsInProgram = false;
break;
}
```
bytInput also used a method switch is in a loop, if you need code more pls ask
