Java Program to print the sum of all the elements of the array - The Coding Shala

Home >> Java Programs >> Sum of Array elements

 In this post, we will write a Java program to print the sum of all the elements of the array.

Java Program to print the sum of all the elements of the array

Write a Java program to find the sum of all the elements of the given integer array.

Example 1:
Input: [1, 2, 3, 4, 5]
Output: 15
Explanation: Sum of all the elements is = 1 + 2 + 3 + 4 + 5 = 15

Approach 1

Using loop we can find the sum of array elements.

Java Program: 

// print sum of all the elements of the array java program

public class Main {
	
	public static int findSum(int[] nums) {
		int sum = 0;
		// Iterate using loop
		for(int i = 0; i < nums.length; i++) {
			sum = sum + nums[i];
		}
		return sum;
	}
	
	public static void main(String[] args) { 
		int[] arr = {1, 4, 7, 9, 10};
		int sum = findSum(arr);
		System.out.println("Sum of all the elements is: " + sum);
	}
}

N-th Tribonacci Number Solution - The Coding Shala

Home >> Programming >> N-th Tribonacci Number  Hey there, welcome back to another post. In this post, we will learn how to solve the N-th Tribonacci Number problem and will implement its solution in Java. N-th Tribonacci Number Problem Statement The Tribonacci sequence Tn is defined as follows: T0 = 0, T1 = 1, T2 = 1, and Tn+3 = Tn + Tn+1 + Tn+2 for n >= 0. Given n, return the value of Tn.  Example 1:  Input: n = 4 Output: 4 Explanation: T_3 = 0 + 1 + 1 = 2 T_4 = 1 + 1 + 2 = 4 N-th Tribonacci Number Java Solution using Bottom-Up DP This problem is similar to the Fibonacci series. We can solve it using the Bottom-Up approach of dynamic programming. Time Complexity: O(n) Space Complexity: O(n) The space complexity can be reduced to O(1) by using variables to store the previous three values instead of using an array. Java Program:  class Solution { public int tribonacci( int n) { if (n == 0) return 0; ...

Java Program to Convert Binary to Decimal - The Coding Shala

Home >> Java Programs >> Convert Binary to Decimal  Hey there, welcome back to another post. In this post, we will learn how to convert Binary to Decimal in Java. Java Program to Convert Binary to Decimal You have given a binary number, convert it to a decimal number. Example:  Input: 101 Output: 5 Input: 111 Output: 7 Binary to Decimal Conversion in Java Approach We will the below formula to convert binary to decimal: decimal number = (2^0) * (rightmost digit) + (2^1) * (second rightmost digit) + ...  for example:  binary number = 110 decimal number = 2^0 * 0 + 2^1 * 1 + 2^2 * 1 = 1 * 0 + 2 * 1 + 4 * 1 = 0 + 2 + 4 = 6 Java Program:  import java.util.Scanner; /** * https://www.thecodingshala.com/ */ public class Main { public static void printDecimal( int num) { int decimal = 0; int twos = 1; // 2^0 = 1 initial value while (num > 0) { ...

LeetCode - Shuffle the Array Solution - The Coding Shala

Home >> LeetCode >> Shuffle the Array  In this post, we will learn how to solve LeetCode's Shuffle the Array problem and will implement its solution in Java. Shuffle the Array Given the array nums consisting of 2n elements in the form [x1,x2,...,xn,y1,y2,...,yn]. Return the array in the form [x1,y1,x2,y2,...,xn,yn]. Example 1: Input: nums = [2,5,1,3,4,7], n = 3 Output: [2,3,5,4,1,7]  Explanation: Since x1=2, x2=5, x3=1, y1=3, y2=4, y3=7 then the answer is [2,3,5,4,1,7]. Example 2: Input: nums = [1,2,3,4,4,3,2,1], n = 4 Output: [1,4,2,3,3,2,4,1] Practice this problem on LeetCode: Click Here. Shuffle the Array Java Solution Approach 1: Using a new Array. Space complexity: O(n). Java Program:  class Solution { public int [] shuffle ( int [] nums , int n ) { int [] ans = new int [ 2 * n ]; int j = 0 ; for ( int i = 0 ; i < 2 * n ; i = i + 2 ){ ans [ i ] = nums [ j ]; ans...

Introduction to Kotlin Programming Language for Backend Development - The Coding Shala

Home >> Learn Kotlin >> Kotlin Introduction Are you looking for a powerful and reliable programming language for backend development? Look no further than Kotlin. Kotlin is a modern, statically typed programming language that has gained a lot of popularity in recent years. In this blog post, we'll take a look at what Kotlin is and why it's a great choice for backend development. What is Kotlin? Kotlin is a statically typed, cross-platform, general-purpose programming language that was developed by JetBrains in 2011. It is designed to be more concise, expressive, and safe than Java, the most widely used programming language for Android development. Kotlin can be compiled to run on the Java Virtual Machine (JVM), JavaScript, and native platforms, making it a versatile language for different types of applications. Why use Kotlin for backend development? Kotlin has several features that make it a suitable language for backend development, such as: Concisenes...
