Why is my program freezing when I use a method? (Java)
- by user2915567
When I use a boolean method in the Main body, my program freezes and stops working. I've tried putting the method at different places but the exact same thing happens - it freezes.
The method is really simple and well-written, I'm not sure what's causing the problem.
P.S. The method is on the bottom of the code.
Thanks for your help!
Edit: That was a dumb question now that I look at it. Thanks again everyone!
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
int stringNumber = 0;
String[] stringArray = new String[10];
for (int i = 0; i <= stringArray.length; i++) {
boolean itemExists = false;
boolean AddItem = AddItem();
if (AddItem == true) {
out.println("\nEnter a string");
String input = keyboard.next();
if (i > 0) {
for (int j = 0; j < stringArray.length; j++) {
if (input.equalsIgnoreCase(stringArray[j])) {
itemExists = true;
out.println("Item \"" + input + "\" already exists.");
break;
}
}
}
if (itemExists == false) {
stringArray[stringNumber] = input;
out.println("\"" + stringArray[stringNumber] + "\"" + " has been stored.\n");
} else {
out.println("Try again.");
i--;
}
PrintArray(stringArray);
stringNumber++;
}
}
}
// This is the method I was talking about //
public static boolean AddItem() {
Scanner keyboard = new Scanner(System.in);
int input = keyboard.nextInt();
out.println("If you want to add an item, Press 1");
if (input == 1) {
return true;
} else {
out.println("Invalid input.");
return false;
}
}
