Finding Minimum, Maximum, and Sum of Array Elements in Java

Java program to initialize given data in an array and find the minimum and maximum values along with the sum of given elements.

import java.util.*;

public class Array_Max_Min {
public static void main() {
Scanner Sc = new Scanner(System.in);
System.out.println(“Enter 5 values”);
int l = 0, s = 9, sum = 0;
int a[] = new int[5];

// Loop to input 5 values and calculate sum
for (int i = 0; i < 5; i++) { a[i] = Sc.nextInt(); sum += a[i]; // Finding maximum value if (Math.max(a[i], l) == a[i]) { l = a[i]; } // Finding minimum value if (Math.min(a[i], s) == a[i]) { s = a[i]; } } // Output the results System.out.println("Minimum value: " + s); System.out.println("Maximum value: " + l); System.out.println("Sum of elements: " + sum); } }

Certainly! Here’s a rephrased version suitable for a blog post:

Finding Minimum, Maximum, and Sum of Array Elements in Java

In this Java tutorial, we’ll create a program that allows us to find the minimum, maximum values, and sum of integers entered by the user. This exercise is useful for understanding basic array operations and conditional statements in Java programming.

Step-by-Step Explanation

1. Importing Necessary Libraries

We begin by importing the Scanner class from java.util, which enables us to read user input efficiently:

import java.util.Scanner;

2. Class and Method Definition

Next, we define a public class named Array_Max_Min with a main method where our program execution begins:

public class Array_Max_Min {
    public static void main(String[] args) {
        // Code goes here
    }
}

3. Variable Initialization

Inside the main method, we initialize variables to store the maximum (l), minimum (s) values, and the sum of all entered integers (sum):

Scanner scanner = new Scanner(System.in);
System.out.println("Enter 5 values:");
int l = Integer.MIN_VALUE; // Initialize l to the smallest possible integer
int s = Integer.MAX_VALUE; // Initialize s to the largest possible integer
int sum = 0;
int[] array = new int[5]; // Create an array to store 5 integers

4. Input Handling and Calculation

We use a loop to read 5 integers from the user, calculate their sum, and determine the minimum and maximum values:

for (int i = 0; i < 5; i++) {
    array[i] = scanner.nextInt();
    sum += array[i];

    // Find maximum value
    if (array[i] > l) {
        l = array[i];
    }

    // Find minimum value
    if (array[i] < s) {
        s = array[i];
    }
}

5. Output Results

Finally, we display the results to the user:

System.out.println("Minimum value: " + s);
System.out.println("Maximum value: " + l);
System.out.println("Sum of elements: " + sum);

Summary

This Java program efficiently computes the minimum, maximum values, and sum of 5 integers entered by the user. It demonstrates fundamental concepts such as array handling, conditional statements (if), and basic arithmetic operations. Feel free to modify and experiment with the code to deepen your understanding of Java programming.
