In this program, we are going to share a Java program to display prime numbers from 1 to n. If you are a Java beginner and want to start learning the Java programming, then keep your close attention in this tutorial as I am going to share how to write a Java program to display prime numbers from 1 to n.
Copy the below Java program and execute it with the help of Javac compiler. At the end of this program, We have shared the output of this program.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 | import java.util.Scanner; class PrimeNumbers2 { public static void main (String[] args) { Scanner scanner = new Scanner(System.in); int i =0; int num =0; String primeNumbers = ""; System.out.println("Enter the value of n:"); int n = scanner.nextInt(); scanner.close(); for (i = 1; i <= n; i++) { int counter=0; for(num =i; num>=1; num--) { if(i%num==0) { counter = counter + 1; } } if (counter ==2) { primeNumbers = primeNumbers + i + " "; } } System.out.println("Prime numbers from 1 to n are :"); System.out.println(primeNumbers); } } |
Enter the value of n:
150
Prime numbers from 1 to n are :
2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89
