In this java program, you’ll learn how to display the prime numbers between two intervals such as 1 to 100 or 1 to nth using a function. In this program, we used the following java basics such as for loop, while loop, and if..else condition.
Here is the program to display the prime number between two intervals using a function.
//Java Program to Display Armstrong Numbers Between Intervals Using Function
import java.util.Scanner;
public class JavaPrograms {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter a Start Number: ");
int low = sc.nextInt();
System.out.println("Enter an End Number: ");
int high = sc.nextInt();
System.out.println("All Armstrong Number Between Interval of " + low + " to " + high + " are:");
while (low < high) {
if (checkPrimeNumber(low))
System.out.print(low + " ");
++low;
}
}
public static boolean checkPrimeNumber(int num) {
boolean flag = true;
for (int i = 2; i <= num / 2; ++i) {
if (num % i == 0) {
flag = false;
break;
}
}
return flag;
}
}
Enter a Start Number:
1
Enter an End Number:
100
All Armstrong Number Between Intervals of 1 to 100 are:
1 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97
