2. Program to find first N primesGiven program uses Java 8 stream apis to find first N prime numbers in series. 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 Number Java Program – Using While Loop 1) In this program, the while loop is present in the constructor. If we instantiate the class then automatically constructor will be executed. 2) Read the “n” value using scanner class object sc.nextInt(). FindPrime class is initiated in the...
The value of the first number and the second number are switched using a temporary variable, as can be seen in the output. 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 ...
We check if num is exactly divisible by any number from 2 to num - 1. If we find a factor in that range, the number is not prime, so we set flag to True and break out of the loop. Outside the loop, we check if flag is True or False. If it is True, num is not a prime...
