Java Program to Find the Mode in a Data Set

This is a java program to find the mode of a set. The mode of a set is defined as the highest occurring element in the set. We count the occurrence of each of the element and print the element whose count is highest.

Here is the source code of the Java Program to Find the Mode in a Data Set. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

//This is a java program to find the mode for a given sequence of numbers

```
import java.util.Random;
```
```
 
```
```
public class Mode 
```
```
{
```
```
    static int N = 20;
```
```
    static int[] sequence = new int[N];
```
```
 
```
```
    public static int mode() 
```
```
    {
```
```
        int maxValue = 0, maxCount = 0;
```
```
 
```

        for (int i = 0; i < sequence.length; ++i)

```
        {
```
```
            int count = 0;
```

            for (int j = 0; j < sequence.length; ++j)

```
            {
```

                if (sequence[j] == sequence[i])

```
                    ++count;
```
```
            }
```
```
            if (count > maxCount) 
```
```
            {
```
```
                maxCount = count;
```
```
                maxValue = sequence[i];
```
```
            }
```
```
        }
```
```
 
```
```
        return maxValue;
```
```
    }
```
```
 
```

    public static void main(String args[])

```
    {
```
```
        Random random = new Random();
```
```
 
```
```
        for (int i = 0; i < N; i++)
```

            sequence[i] = Math.abs(random.nextInt(100));

```
 
```

        System.out.println("The set of numbers are: ");

```
        for (int i = 0; i < N; i++)
```

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

```
 
```

        System.out.println("\nThe mode of the set is: " + mode());

```
    }
```
```
}
```

Output:

$ javac Mode.java
$ java Mode
 
The set of numbers are: 
85 3 80 56 37 47 13 11 94 38 6 12 10 31 52 67 81 98 43 37 
The mode of the set is: 37
