# Java Program to Display the Prime Numbers Between Two Intervals

###### Tutorialsrack 04/07/2021 Java

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. 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.

##### Code - Java Program to Display the Prime Numbers Between Two Intervals
``````//Java Program to Display Prime Numbers Between Two Intervals

import java.util.Scanner;

public class JavaPrograms {

public static void main(String[] args) {
int low, high;

Scanner sc = new Scanner(System.in);

System.out.println("Enter a Start Number: ");
low = sc.nextInt();

System.out.println("Enter an End Number: ");
high = sc.nextInt();

System.out.println("All Prime Number Between Interval of " + low + " to " + high + " are:");

while (low < high) {
boolean flag = false;

for (int i = 2; i <= low / 2; ++i) {
// condition for non-prime number
if (low % i == 0) {
flag = true;
break;
}
}

if (!flag && low != 0 && low != 1)
System.out.print(low + " ");

++low;
}
}
}``````
##### Output

Enter a Start Number:

20

Enter an End Number:

80

All Prime Number Between Interval of 20 to 80 is:

23 29 31 37 41 43 47 53 59 61 67 71 73 79
