Write a Java program to find Number is Prime number or not from 1 To N.
Input:
Enter the N: 20
Output:
Prime nos from Given Range :
2
3
5
7
11
13
17
19
no of prime number in list: 8
Enter the N: 20
Output:
Prime nos from Given Range :
2
3
5
7
11
13
17
19
no of prime number in list: 8
Code In java:
import java.util.Scanner;
public class Prime{
public static void main(String[] args) {
Scanner scan = new java.util.Scanner(System.in);
System.out.println("Enter the N: ");
int N=scan.nextInt();
int count,count2=0,temp;
System.out.println("Prime nos from Given Range :");
//condition used to identify number is odd or even
for(temp=1;temp<=N;temp++)
{
count=0;
for(int j=1; j<=temp; j++)
{
if(temp%j==0)
{
count++;
}
}
if(count==2)
{
System.out.println(temp);
count2++;
}
}
System.out.println("no of prime number in list: " + count2);
}
}
Output:
Enter the N:
20
Prime nos from Given Range :
2
3
5
7
11
13
17
19
no of prime number in list: 8
