The blog provides the technical approach on ” How to get difference of minimum and maximum array element ?”
Problem Statement:
How to identify the minimum array element, maximum array element and difference of minimum and maximum array elements in java
Technical Approach:
- Get the Array Count as User Input
- Get the Array Elements as User Input
- Iterate the Array Elements
- Compare Array Elements to get the minimum element
- Compare Array Elements to get the maximum element
- Calculate the difference of minimum and maximum element
package com.java.planforexams.array;
import java.util.Scanner;
public class DiffBWMinMaxArrayElement {
public static void main(String[] args) {
// Scanner object for reading User Input
Scanner scan = new Scanner(System.in);
int count;
int minArrayElement =0;
int maxArrayElement =0;
// Receive the Array Element Count from User
System.out.print("Provide the Array Element Count : ");
// Get the Array Count
count = scan.nextInt();
//Set the Array Size with Count value
int arrayInputFromUser[] = new int[count];
// Receive the Array Elements from User.
System.out.println("Enter the elements:");
// Iterate the array elements
for (int incr=0; incr<count; incr++)
{
arrayInputFromUser[incr] = scan.nextInt();
}
minArrayElement=arrayInputFromUser[0];
maxArrayElement=arrayInputFromUser[0];
for(int i=1;i<count;i++)
{
if(arrayInputFromUser[i]>maxArrayElement)
{
maxArrayElement=arrayInputFromUser[i];
}
if(arrayInputFromUser[i]<minArrayElement)
{
minArrayElement=arrayInputFromUser[i];
}
}
System.out.println("Minimum Array element is :" + minArrayElement);
System.out.println("Maximum Array Element is :" + maxArrayElement);
int arrayElmentDiff = maxArrayElement -minArrayElement ;
System.out.print("Difference between Minimum and Maximum in array is : " + arrayElmentDiff);
}
}
Output:
Provide the Array Element Count : 5
Enter the elements:
12
12
32
32
34
Minimum Array element is :12
Maximum Array Element is :34
Difference between Minnimum and Maximum in array is : 22
