# Java program to find all prime numbers in the given range

## Write a Java program to find all prime numbers in the given range – Java Tutorial

### Problem Statement

Write a Java program to find all prime numbers in the given range.

## Solution:

A number is said to be a prime number if it is divisible by itself or by 1reverse is equal to the original number.

For example,

The number 13 is a prime number, as it is divisible by itself and by 1.

The number 12 is not a prime number as it is divisible by itself, 1 and also 2, 3, 4, and 6. Hence 12 is not a prime number

Step to get all prime numbers in a given range in Java.

First, create a class named PrimeInRange and add the main method to it.

Next, set the value of the flag to 0 indicating a number is a prime number.

Read the minimum and maximum value of the range from the user using an object of scanner class object.

Starting from minimum to maximum consider one number at a time and check whether the number is divisible by any other except itself or 1. If the number is divisible by any other number except itself or 1, then set the value of the flag to 1 and break the loop.

If the value of the flag is equal to 0 then print, the number is a prime number, or print the number is not a prime number using the statement System.out.println

import java.util.Scanner;

public class PrimeInRange
{
public static void main(String args[])
{
int min, max, flag = 0;
Scanner in = new Scanner(System.in);
System.out.println("Enter the minimum value:");
min = in.nextInt();
System.out.println("Enter the Maximum value:");
max = in.nextInt();
for (int n=min; n<=max;n++)
{
for (int i = 2; i<n; i++)
{
if (n%i==0)
{
flag = 1;
break;
}
}
if (flag == 0)
{
System.out.print(n+ " ");
}
flag = 0;
}
}
}
```

### The output of the Prime Number Program in Java

Case 1:

Enter a number: 13

13 is a prime number

Case 2:

Enter a number: 121

121 is not a prime number
