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

Java Basic: Exercise-54 with Solution

Write a 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.

Sample Solution:

Java Code:

import java.util.*;
 public class Exercise54 {
 public static void main(String[] args)
    {
        Scanner in = new Scanner(System.in);
        System.out.print("Input the first number : ");
        int x = in.nextInt();  
		System.out.print("Input the second number: ");
		int y = in.nextInt(); 
		System.out.print("Input the third number : ");
        int z = in.nextInt(); 
        System.out.print("The result is: "+test_last_digit(x, y, z,true));
		System.out.print("\n");
    }
   
    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

Java: Tips of the Day

Execution of console commands:

Java allows you to execute console commands directly from code using a class Runtime. It is very important not to forget about exception handling.

For example, let's try to open a PDF file through a Java terminal:

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
  
public class ShellCommandExec {
  
  public static void main(String[] args) {
    String gnomeOpenCommand = "gnome-open //home//user//Documents//MyDoc.pdf";
  
    try {
      Runtime rt = Runtime.getRuntime();
      Process processObj = rt.exec(gnomeOpenCommand);
  
      InputStream stdin = processObj.getErrorStream();
      InputStreamReader isr = new InputStreamReader(stdin);
      BufferedReader br = new BufferedReader(isr);
  
      String myoutput = "";
  
      while ((myoutput=br.readLine()) != null) {
        myoutput = myoutput+"\n";
      }
      System.out.println(myoutput);
    }
    catch (Exception e) {
      e.printStackTrace();
    }
  }
}
