In this article, we will understand how to calculate the compound interest. Compound interest is calculated using the following formula − Principle*(1+(rate / 100))^time – Principle Compound Interest − The percentage interest charged on principal and accrued interest. Rates are higher compared to simple interest. Problem Statement Write a Java program to calculate the compound interest using the formula. Below is a demonstration of the same − Input Enter a Principle number : 100000 Enter Interest rate : 5 Enter a Time period in years : 3 Output The Compound Interest is : 15762.50000000001 Algorithm Below are the steps to ...

The agenda of this article is to write a Java program to calculate simple interest. But, before doing it programmatically, let's understand how we calculate simple interest mathematically. The simple interest is a technique to determine the amount of interest gained on a principal amount at the specified interest rate for a given time period. Unlike compound interest, its principal amount does not change over time. To calculate Simple Interest, we use the following formula − Simple Interest (S.I) = Principal * Time * Rate / 100 Below is a demonstration of the same − Input Enter a Principle ... Read More

In this article, we will understand how to find even sum of Fibonacci Series till number N. A Fibonacci series is sequence of numbers formed by the sum of its two previous integers. An even Fibonacci series is all the even numbers of the Fibonacci series.Fibonacci series generates the subsequent number by adding two previous numbers. Fibonacci series starts from two numbers − F0 & F1. The initial values of F0 & F1 can be taken 0, 1 or 1, 1 respectively.Fn = Fn-1 + Fn-2Hence, a Fibonacci series can look like this −F8 = 0 1 1 2 3 ... Read More

In this article, we will understand how to display all the prime numbers from 1 to N in Java. All possible positive numbers from 1 to infinity are called natural numbers. Prime numbers are special numbers who have only two factors 1 and itself and cannot be divided by any other number.A number is a prime number if its only factors are 1 and itself. 11 is a prime number. Its factors are 1 and 11 itself. Some examples of prime numbers are 2, 3, 5, 7, 11, 13 and so on. 2 is the only even prime number. All ... Read More

In this article, we will understand how to get an input from user in Java. This achieved using a scanner object. The Scanner.nextInt() method is used to get the input.The java.util.Scanner.nextInt() method Scans the next token of the input as an int. An invocation of this method of the form nextInt() behaves in exactly the same way as the invocation nextInt(radix), where radix is the default radix of this scanner.Below is a demonstration of the same −InputSuppose our input is −Hello, I am John!OutputThe desired output would be −The input string is: Hello, I am John! AlgorithmStep1- Start Step 2- ... Read More
