Java conditional statement Exercises: Display the multiplication table of a given integer

Sample Solution:

Java Code:

import java.util.Scanner;
public class Exercise14 {

   public static void main(String[] args)

{
   int j,n;

   System.out.print("Input the number(Table to be calculated): ");
{
   System.out.print("Input number of terms : ");
    Scanner in = new Scanner(System.in);
		    n = in.nextInt();

   System.out.println ("\n");
   for(j=0;j<=n;j++)
  
     System.out.println(n+" X "+j+" = " +n*j);
   }
}
}

Sample Output:

Input the number(Table to be calculated): Input number of terms : 5                                           
5 X 0 = 0                                                                                                     
5 X 1 = 5                                                                                                     
5 X 2 = 10                                                                                                    
5 X 3 = 15                                                                                                    
5 X 4 = 20                                                                                                    
5 X 5 = 25

Java: Tips of the Day

IsPowerOfTwo

Checks if a value is positive power of two.

To understand how it works let's assume we made a call IsPowerOfTwo(4).

As value is greater than 0, so right side of the && operator will be evaluated.

The result of (~value + 1) is equal to value itself. ~100 + 001 => 011 + 001 => 100. This is equal to value.

The result of (value & value) is value. 100 & 100 => 100.

This will value the expression to true as value is equal to value.

public static boolean isPowerOfTwo(final int value) {
    return value > 0 && ((value & (~value + 1)) == value);
}
