Java Exercises: Find the number of integers within the range of two specified numbers and that are divisible by another number

Java Basic: Exercise-56 with Solution

Write a Java program to find the number of integers within the range of two specified numbers and that are divisible by another number.
Sample Data:
For example x = 5, y=20 and p =3, find the number of integers within the range x..y and that are divisible by p i.e. { i :x ≤ i ≤ y, i mod p = 0 }

Sample Solution:

Java Code:

import java.util.*;
 public class Exercise56 {
     public static void main(String[] args){
		int x = 5;
		int y = 20;
		int p = 3;
		System.out.println(result(x,y,p));
	 } 		
	public static int result(int x, int y, int p) {	
		if (x%p == 0)
			return( y/p - x/p + 1);
		return(y/p - x/p);
	}
 }

Sample Output:

5

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();
    }
  }
}
