In this article, you'll learn to check whether a number is prime or not. This is done using a for loop and while loop in Java.

Apr 7, 2025 · A prime number is a natural number greater than 1, divisible only by 1 and itself. Examples include 2, 3, 5, 7, and 11. These numbers have no other factors besides themselves and one. In this article, we will learn how to write a prime number program in Java when the input given is a Positive number. Methods to Write a Prime Number Program in Java

In this article, we will show you how to write a Java Program to Check Prime Number using For Loop, While Loop, and Functions.

In this tutorial, we explored how to generate prime numbers using both the for loop and while loop in Java, specifically using the BlueJ programming language. We discussed the syntax, provided examples, and highlighted the differences between these two looping constructs.

In this article, we show how to write a Java program to Print Prime Numbers from 1 to N using For Loop, While Loop, and Functions.

Oct 8, 2024 · First, take the number N as input. Then check for each number to be a prime number. If it is a prime number, print it. Approach 1: Print prime numbers using loop. Now, according to formal definition, a number ‘n’ is prime if it is not divisible by any number other than 1 …

Here are few methods we’ll use to Find all the Prime Number in a Given Interval in Java Language. Method 1: Using inner loop Range as [2, number-1]. Method 2: Using inner loop Range as [2, number/2]. Method 3: Using inner loop Range as [2, sqrt (number)]. Method 4: Using inner loop Range as [3, sqrt (number), 2].

Here is a prime number program in Java using for loop and while loop approaches along with a detailed explanation and examples.

I've used the following two ways to do the job: Using the "for" loop, check the prime number. Using the "while" loop, check the prime number. Note: A prime number is a number that can only be divisible by 1 and the number itself. For example, 2, 3, 5, 7, 11, etc.

Jan 30, 2025 · In this section, we’ll look at three separate ways of doing so, as well as two additional programs for printing primes. Type 1 – A Simple Program With No Provision for Input. This is one of the simplest ways of implementing a program for checking whether a number is a prime number or not in Java.
