Question

I have to fill out the code for Team.java 

10.12 LAB: Winning team (classes)

Given `main()`, define the Team class (in file Team.java). For class method `getWinPercentage()`, the formula is:
\[ \text{wins} / (\text{wins} + \text{losses}) \]
*Note:* Use casting to prevent integer division.

For class method `printStanding()`, output the win percentage of the team with two digits after the decimal point and whether the team has a winning or losing average. A team has a winning average if the win percentage is 0.5 or greater.

**Example:**

If the input is:
```
Ravens
13
3
```
where Ravens is the team's name, 13 is the number of team wins, and 3 is the number of team losses, the output is:
```
Win percentage: 0.81
Congratulations, Team Ravens has a winning average!
```

**Example:**

If the input is:
```
Angels
80
82
```
the output is:
```
Win percentage: 0.49
Team Angels has a losing average.
```

```java
import java.util.Scanner;

public class WinningTeam {
    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);
        
        Team team = new Team();
        
        String name = scnr.next();
        int wins = scnr.nextInt();
        int losses = scnr.nextInt();
        
        team.setName(name);
        team.setWins(wins);
        team.setLosses(losses);

    }
}
```

### Explanation

This Java code defines a class named `WinningTeam` with a main method that serves as the entry point for the program. It performs the following steps:

1. **Import Statement**: 
   - `import java.util.Scanner;` imports the Scanner class from the `java.util` package, necessary for reading input from the user.

2. **Class Definition**:
   - `public class WinningTeam` declares the class `WinningTeam`.

3. **Main Method**:
   - `public static void main(String[] args)` signifies the main method where the program execution begins.

4. **Scanner Initialization**:
   - `Scanner scnr = new Scanner(System.in);` initializes a Scanner object to read user input from the console.

5. **Team Object Creation**:
   - `Team team = new Team();` creates a new instance of a `Team` class.

6. **Input Reading**:
   - `String name = scnr.next();` reads a String input for the team's name.
   - `int wins = scnr.nextInt();` reads an integer input for the number of wins.
   - `int losses = scnr.nextInt();` reads an integer input for the number of losses.

7. **Setting Team Details**:
   - `team.setName(name);` sets the team name.
   - `team.setWins(wins);` sets the number of wins.
   - `team.setLosses(losses);` sets the number of losses.

8. **Printing the Standings**:
   - `team.printStanding();` is called to print the team's standings.

### Note
This snippet assumes the existence of a `Team` class with methods `setName`, `setWins`, `setLosses`, and `printStanding()`. These methods are not defined within this snippet but are crucial for the code to function correctly.
