    • How to calculate prime numbers in Java?

    for loop iterates from i=1 to n.

  • If remainder of n,i is 0 then count value increased by 1. Count represents total no of divisors.
  • if count=2 then the given number is prime.

    • How to generate prime numbers in JavaScript?

    The first for loop is used to loop between the numbers provided by the user.

  • A variable flag is set to 0.
  • The second for loop is used to loop between 2 to the number that is stored in i.
  • Inside the second loop,the value of i is divided by each number from 2 to value one less than i (i – 1).

    • How to find the nth prime number in Java?

    Take value of n from user using Scanner class.

  • Intialize a variable count. It will keep track of number of prime number processed so far.
  • Intialize a variable i. It will keep track of current number.
  • Iterate over while loop until count ! = n Increment i by 2 as even numbers are not prime Check if number is prime.
  • Return i which is nth prime number.
