Given N integer numbers and we have to find mean of all numbers using java program.

Example 1:

Input:
Entered numbers: 63, 25, 45
Output:
Mean of the given numbers is : 44

Program to find mean of given numbers in java

import java.util.Scanner;

public class CalculateMean
{
    public static void main(String args[])
    {
    	// initialize and declaring the objects.
        int n, i, sum=0, mean;
        int arr[] = new int[50];
        Scanner scan = new Scanner(System.in);
		
        // enter number you have to enter.
        System.out.print("How many Number you want to Enter : ");
        n = scan.nextInt();
		
        // enter the numbers.
        System.out.println("Enter " +n+ " Numbers : ");
      
        // this will access all numbers and make sum of the numbers.
        for(i=0; i<n; i++)
        {
            arr[i] = scan.nextInt();
            sum = sum + arr[i];
        }
        // fomula to calculate mean.
        mean = sum/n;
        System.out.print("Mean of the given numbers is : " +mean);
    }
}

Output

First run:
How many Number you want to Enter : 5
Enter 5 Numbers : 
25
36
95
52
58
