Java: Accepts three integers from the user and return true if two or more of them have the same rightmost digit


Same Rightmost Digit Check

Write a Java program that accepts three integers from the user and returns true if two or more of them (integers) have the same rightmost digit. The integers are non-negative.

Sample Solution:

Java Code:

import java.util.*;

public class Exercise54 {
    public static void main(String[] args) {
        // Create a Scanner object for user input
        Scanner in = new Scanner(System.in);

        // Prompt the user to input the first number
        System.out.print("Input the first number: ");
        int x = in.nextInt();

        // Prompt the user to input the second number
        System.out.print("Input the second number: ");
        int y = in.nextInt();

        // Prompt the user to input the third number
        System.out.print("Input the third number: ");
        int z = in.nextInt();

        // Prompt the user to input a boolean value (true or false)
        System.out.print("Input a boolean value (true/false): ");
        boolean xyz = in.nextBoolean();

        // Calculate the result using the test_last_digit function and display it
        System.out.print("The result is: " + test_last_digit(x, y, z, xyz));

        // Print a new line for better formatting
        System.out.print("\n");
    }

    // Function to test if any two numbers have the same last digit based on the boolean input
    public static boolean test_last_digit(int p, int q, int r, boolean xyz) {
        return (p % 10 == q % 10) || (p % 10 == r % 10) || (q % 10 == r % 10);
    }
}

Sample Output:

Input the first number : 5                                             
Input the second number: 10                                            
Input the third number : 15                                            
The result is: true

Flowchart:

Flowchart: Java program that accepts three integers from the user and return true if two or more of them (integers ) have the same rightmost digit. The integers are non-negative.

For more Practice: Solve these Related Problems:

  • Modify the program to check for leftmost digit instead.
  • Write a program that finds numbers with the same sum of digits.
  • Check if all digits in a number are the same.
  • Find numbers that have the same second-to-last digit.

Java Code Editor:

Previous: Write a Java program that accepts three integers from the user and return true if the second number is greater than first number and third number is greater than second number.
Next: Write a Java program to convert seconds to hour, minute and seconds.
