### Java Program to Print Sum of given Array Elements

In previous  post we learnt how to check given element is present in array or not. In this post we will learn how to print sum of given array elements. So let's get started... :)

### Step by step logic of the given program:

1. Accept array limit from user store it in variable say lim.

2. Accept elements from user. Run a for loop from 0 to arr.length-1 and store elements one by one in array:

### Java Program to Check whether Given Element is Present in Array or not

In previous tutorial we learnt how to accept and print array elements. In this post we will learn is given element is present in array or not, Java program to check whether given element is present in array or not.

## Factorial Program in Java:

Factorial of a number means the product of all positive descending integers.
for example: If we want to calculate factorial of 5 then it will be written as
5 x 4 x 3 x 2 x 1 = 120 . So 120 is the factorial of  5.

## Fibonacci Series In Java:

The fibonacci series is a series where the next number is the sum of previous two numbers.
for examples:  0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 etc

above you can see first two numbers of fibonacci series are 0 and 1.

### Java program to calculate gross salary of an employee

Ex: Write a java program to calculate gross salary of an employee. How to write a java program to calculate gross salary of an employee using DA and HRA. Java program to calculate gross salary of an employee using DA and HRA.

We can calculate gross salary   of an  employee using following DA and HRA. The  DA is   20%   of   the   basic   salary   while   the   HRA   is   30%   of   the   basic salary and gross salary is addition of basic salary, DA and HRA.

# EX: Write a Java Program to check given number is prime or not.

## What is prime number?

Prime number is a number that is greater than 1 and divided by 1 and itself only.
For example: 2, 3, 5, 7, 11, 13, 17, 19, 23... etc. are prime numbers.

## EX: Write a java program to check given number is palindrome or not. How to write a java program to check palindrome number.

### What is Palindrome Number?

A palindrome number is a number that is same after reverse. For example: 252, 676, 77577, 1234321 etc.
