# GameListAssigment
This Java program manages a collection of games using an ArrayList. It allows users to perform various operations such as listing all games, searching for a specific game, adding a new game, replacing an existing game, and exiting the program.
## How to Use
1. **Print All Games**
- Choose option 1 to display a list of all games in the collection.
2. **Search for a Game**
- Choose option 2 to search for a game by name. Enter the name, and the program will indicate whether the game exists in the collection.
3. **Add a New Game**
- Choose option 3 to add a new game to the collection. Enter the name of the new game.
4. **Replace a Game**
- Choose option 4 to replace an existing game. Enter the name of the game you want to replace and the name of the new game.
5. **Exit the Program**
- Choose option 5 to exit the program.
## Code Explanation
### Main Class (`Main.java`)
- **ArrayList Initialization:**
```java
ArrayList gameCollection = new ArrayList<>();
An ArrayList named `gameCollection` is created to store instances of the `Game` class.
### Menu Handling:
```java
while (true) {
// Display menu options and read user choice
int choice = scanner.nextInt();
// Switch statement to handle user choices
switch (choice) {
// Cases 1-5 handle different operations
// ...
default:
System.out.println("Ogitligt val. Försök igen.");
break;
}
}
```
The program uses a `while` loop to repeatedly display a menu, read the user's choice, and execute the corresponding operation using a `switch` statement.
### Game Class (`Game.java`)
## Game Class
```java
class Game {
String namn;
public Game(String namn) {
this.namn = namn;
}
@Override
public String toString() {
return namn;
}
}
```
The `Game` class represents a game and has a constructor to set its name. The `toString` method is overridden to provide a string representation of the game.
