print list of prime numbers in java code example
Example 1: making list of prime numbers java
Now let’s see print first 10 prime numbers in java.
public class FirstTenPrimeNumbers
{
public static void main(String[] args)
{
int count = 0, number = 0, a = 1, b = 1;
while(number < 10)
{
b = 1;
count = 0;
while(b <= a)
{
if(a%b == 0)
count++;
b++;
}
if(count == 2)
{
System.out.printf("%d ", a);
number++;
}
a++;
}
}
}
Example 2: java program to find prime number between 1 and 100
class PrimeNumbers
{
public static void main (String[] args)
{
int i =0;
int num =0;
String primeNumbers = "";
for (i = 1; i <= 100; 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 100 are :");
System.out.println(primeNumbers);
}
}
