In Java, to print maximum among two numbers we can use conditional statements such as if else or switch statements. Here we are using switch statement to print maximum among two. For example, if the input numbers are 4 and 5, then 5 is the maximum number. In this article we will learn how to … Read more

In Java, to print all uppercase alphabets we can use loop concepts such as while loop or for loop. If the input alphabet is A, then the output will be A, B, C…. and Z. If the input alphabet (character) is E, then then output will be E, F, G, ….. till Z. Here, the … Read more

In Java, to print all even numbers in a given range we can use loop concepts such as while loop or for loop. When the user enters any two values, it will print all the even numbers in the range that the user entered. Here inputs are inclusive. For a given input range, suppose 1-10, … Read more

In java, to print Fibonacci series using recursion of a given number we can use loop concepts such as for loop and while loop. Fibonacci number is a number which is equals to the sum of its previous two numbers until nth term (except the first two numbers) provided by the user. If user enters … Read more

The Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones, usually starting with 0 and 1. In Java, there are multiple ways to generate the Fibonacci series, and one of the most efficient methods is the iterative approach. In this tutorial, we will explore how to … Read more

In Java, to print ASCII (American Standard Code for Information Interchange) character with values we can use looping concepts such as while loop or for loop and we can also achieve ASCII character with value without using any methods or loops. Java internally converts the character value to an ASCII value. ASCII value is a … Read more

In Java, to print all lowercase alphabets we can use loop concepts such as while loop or for loop. If the input alphabet is a, then the output will be a, b, c…. and z. If the input alphabet (character) is d, then then output will be d, e, f, g, ….. till z. Here, … Read more

In Java, to check whether a given number is prime or not we can use loop concepts such as while loop and for loop. Prime number is a number that is divisible by 1 and itself. For example 2, 3, 5, 7, 11,….. are prime numbers. But 4, 6, .. are not because it is … Read more

In Java, to check a given number is Armstrong or not we can use loop concepts such as while loop or for loop. Armstrong numbers are positive n-digit numbers that are equal to the sum of their digits’ nth powers. Here n is the count of digits in input number. For example 153 is an Armstrong … Read more

In Java, to check a given number is strong or not we can use loop concepts such as while loop or for loop. For given integer input value, find the sum of the factorials of individual digits. If sum of individual factorials of digits is equal to the original number we say that is a … Read more
