Question

Fill an array (type int, size n).

Print the max and the elements min and their position.

Answer 1

import java.util.*;
class clArrays
{
    public void main()
    {
        Scanner sc = new Scanner(System.in);        
        System.out.print("Enter the array size : ");
        int n = sc.nextInt();        
        int R[] = new int[n];
        int j = 0;        
        System.out.print(" Enter the elements : \n");
        for(j = 0; j < n; j++)
        {
            System.out.print("Enter value for cell number " + j + " : ");
            R[j] = sc.nextInt();
        }        
        int min = R[0], minp = 0;
        for(j = 1; j < n; j++)
        {
            if(min > R[j])
            {
                min = R[j];
                minp = j;
            }
        }        
        int max = R[0], maxp = 0;
        for(j = 1; j < n; j++)
        {
            if(max < R[j])
            {
                max = R[j];
                maxp = j;
            }
        }        
        System.out.println(" Largest Element is : " + max + " at position " + maxp);
        System.out.println(" Smallest Element is : " + min + " at position " + minp);
    }
}

Output:

Enter the array size: 8

Enter the elements :

Enter value for cell number 0 : 55

Enter value for cell number 1: 66

Enter value for cell number 2 : 44 

Enter value for cell number 3 : 22 

Enter value for cell number 4 : 88 

Enter value for cell number 5 : 11 

Enter value for cell number 6 : 99 

Enter value for cell number 7 : 77 

Largest Element is : 99 at position 6

Smallest Element is : 11 at position 5
