Check Divisibility by 5 in Java

In mathematics, the divisibility rule of 5 states that if the number ends with 0 or 5 then it will divisible by 5. There is another way to identify the divisibility rule of 5, if the remainder comes to 0 it returns the number is divisible by 5. The mod(%) operator is normally used in programming when it comes to divisibility.

Following are some examples which helps you to understand the divibility rule of 5 ?

• Given number is 525, the number ends with 5 and it is divisible by 5.
• Given number is 7050, the number ends with 0 and it is divisible by 5.
• Given number is 678, the number does not end with 0 and 5 and it is not divisible by 5.

In this article, we are going to solve whether the number is divisible by 5 using Java.

Algorithm

Following are the steps that determine how to solve this problem statements ?

• We will use the package java.util.* to take user input of primitive data type.
• Start with the main class, and initialize the integer variable to store the input integer.
• Then divide the integer variable by 5 using the mod(%) operator.
• Finally, print the result.

Example 1

In this program, we are going to use an if-else statement to check whether the number divisibility by 5.

import java.util.*;
public class Check_Divisiblity_of_five {
   public static void main(String[] args) {
      int number = 590;
      if (number % 5 == 0)
         System.out.println(number+ "\tis the number is divisible by 5");
      else
         System.out.println(number+ "\tThe number is not divisible by 5");
   }
}

Output

The above code produces the following output ?

590 is the number is divisible by 5

Example 2

Below the program check the divisibility rule of 5 with the help of '!=' operator.

import java.util.*;
public class Check_Divisible_five {
   public static void main(String[] args) {   
      int n = 109;
      if(n % 5 != 0) {
         System.out.println(n+"\t is the number not divisible by 5");
      } else {
         System.out.println(n+"\t is the number divisible by 5");
      }
   }
}

Output

The above code produces the following output ?

109 is the number not divisible by 5

Example 3

In this program, we set the number range between 50-100 and check whether the number is divisible by 5.

import java.util.Scanner;
public class Divisible_by_five {
   public static void main(String []args) {
      for(int n = 50; n <= 100; n++){
         if(n % 5 == 0) {
            System.out.println("The number is divisible by 5 :\t"+ n);
         }
      }
   }
}

Output

The above code produces the following output ?

The number is divisible by 5 :	50
The number is divisible by 5 :	55
The number is divisible by 5 :	60
The number is divisible by 5 :	65
The number is divisible by 5 :	70
The number is divisible by 5 :	75
The number is divisible by 5 :	80
The number is divisible by 5 :	85
The number is divisible by 5 :	90
The number is divisible by 5 :	95
The number is divisible by 5 :	100

Conclusion

The above different codes of Java illustrated the divisibility rule of 5. It shows the importance of various operators like mod(%) and not equal to(!=). Thus, while solving these types of problem statements you must be aware of the divisibility rules.
