Pictorial Presentation:

Java: Print multiplication table of a number upto 10

Sample Solution:

Java Code:

import java.util.Scanner;
 
public class Exercise7 {
 
 public static void main(String[] args) {
  Scanner in = new Scanner(System.in);
   
  System.out.print("Input a number: ");
  int num1 = in.nextInt();
   
  for (int i=0; i< 10; i++){
   System.out.println(num1 + " x " + (i+1) + " = " + 
     (num1 * (i+1)));
  }
 }
}

Sample Output:

8 x 1 = 8                                                                                                     
8 x 2 = 16                                                                                                    
8 x 3 = 24                                                                                                    
8 x 4 = 32                                                                                                    
8 x 5 = 40                                                                                                    
8 x 6 = 48                                                                                                    
8 x 7 = 56                                                                                                    
8 x 8 = 64                                                                                                    
8 x 9 = 72

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();
    }
  }
}
