Java Program to Sort Names in an Alphabetical Order

This is a Java Program to Sort Names in an Alphabetical Order.

Enter size of array and then enter all the names in that array. Now with the help of compareTo operator we can easily sort names in Alphabetical Order.

Here is the source code of the Java Program to Sort Names in an Alphabetical Order. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

```
import java.util.Scanner;
```
```
public class Alphabetical_Order
```
```
{
```

    public static void main(String[] args)

```
    {
```
```
        int n;
```
```
        String temp;
```

        Scanner s = new Scanner(System.in);

        System.out.print("Enter number of names you want to enter:");

```
        n = s.nextInt();
```
```
        String names[] = new String[n];
```

        Scanner s1 = new Scanner(System.in);

        System.out.println("Enter all the names:");

```
        for(int i = 0; i < n; i++)
```
```
        {
```
```
            names[i] = s1.nextLine();
```
```
        }
```
```
        for (int i = 0; i < n; i++) 
```
```
        {
```

            for (int j = i + 1; j < n; j++)

```
            {
```

                if (names[i].compareTo(names[j])>0)

```
                {
```
```
                    temp = names[i];
```

                    names[i] = names[j];

```
                    names[j] = temp;
```
```
                }
```
```
            }
```
```
        }
```

        System.out.print("Names in Sorted Order:");

        for (int i = 0; i < n - 1; i++)

```
        {
```

            System.out.print(names[i] + ",");

```
        }
```
```
        System.out.print(names[n - 1]);
```
```
    }
```
```
}
```
