Prime Number program in Java will print the prime numbers between 1 to any given number. Prime Number is a number that is not divisible by any number other than 1 or itself. Similar logic is used in program will displaying the result. The following is a simple program, which automatically prints prime number starting from 1 to 50.

Prime Number is a number that is not divisible by any number other than 1 or itself. Similar logic is used in program will displaying the result.
At first PrimeNumber class is defined. We create a main() method. Here in the example we have taken 50 as the value of int, programmers can use any value here. Then for loop is created.
The following is a simple program, which automatically prints Prime Number starting from 1 to 50.
Example of Prime Number program in Java:package Tutorial;
public class PrimeNumber {
public static void main(String[] args) {
int num = 50;
System.out.println("prime number from 1 to " + num );
for (int i = 1; i < 50; i++) {
boolean b = true;
for (int j = 2; j < i; j++) {
if (i % j == 0) {
b = false;
break;
}
}
if (b)
System.out.print(i + " ");
}
}
}
Output:
Prime Number from 1 to 50
1 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47
