In this program, user is asked an input where he chooses to input the number of primes he wants to generate.E.g. if user enters 100 then program will generate first 100 prime numbers (starting with 2).package com.howtodoinjava.example; import java.util.List; import java.util.Scanner; ...

Swap Two Numbers in Java Without Using a Temporary Variable Previously, we observed the use of a temporary variable to swap two numbers in Java. Let’s now examine a Java method for swapping two numbers without the use of a temporary variable. Using Arithmetic Addition and Subtraction We learn...
In this tutorial, we will write a Java program to display alternate prime numbers upto a given value. Java Example to print alternate prime numbers In the following example we have two user defined methods: checkPrime() and printAltPrime(). The checkPrim
We will learn about the stack class in Java, how to create a stack, different methods of a stack in Java, and how to iterate over a stack in Java.
Java program to count total positives, negatives and zeros from an array Java program to access elements of character array using for each loop Java program to find the length of an array Java program to find prime and non-prime numbers in the array ...
Java Copy How does the Program Work? Factorial Function: The factorial(int num) method calculates the factorial of a number. It multiplies all numbers from 1 to Checking for Strong Number: The isStrongNumber(int number) method checks if the number is a Strong Number. It does this by. Ex...
Java Code Miles Per Gallon In this method, the entire logic along with the input output operations is written in the main method of the Java Class. For any problem, the first step is to take inputs as desired followed by the necessary steps to be taken and operations to be performed to...
