Nov 10, 2020 · Java Program to print prime numbers using while loop. And also example to print prime numbers from 1 to 100 (1 to N)

public void isPrime(int n) { int i = 2; while (i <= (n - 1)) { if (n % i == 0) { System.out.println("It's not a prime number"); break; } else { System.out.println("It's a prime number"); break; } i++; } }

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

Write a Java Program to Print Prime Numbers from 1 to N using For Loop, While Loop, and Functions. This program allows the user to enter any integer value. Next, this program displays all the Prime numbers from 1 to 100 using For Loop. TIP: Please refer Check Prime Number article in Java to understand the steps involved in checking Prime Number.

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.

Dec 24, 2021 · This is the simplest way to calculate if an integer n is probably a prime: if (n < 2) return false; BigInteger bigInt = BigInteger.valueOf(n); return bigInt.isProbablePrime(100); You can insert this function call in a loop where you can pass a new number every iteration.

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 5, 2018 · Inside this loop you will process some stuff to determine if x is a prime number or not. This stuff your code do is to iterate through all the number from 2 to x and try for each one if it divides x. The variable y is this second number.

Write a Java Program to Check Prime Number using For Loop, While Loop, and Functions. Prime Numbers are any natural number not divisible by any other number except 1 and itself.

Java Program to Print Prime Numbers - This article covers multiple programs in Java to print prime numbers. Print prime numbers from 1 to 100, Print first 10 prime numbers, Print prime numbers from 1 to n Print prime numbers in given range, Print prime numbers using while loop
