Java: Display the multiplication table of a given integer
Java Conditional Statement: Exercise-14 with Solution
Write a Java program to display the multiplication table of a given integer.
Test Data
Input the number (Table to be calculated) : Input number of terms :5
Pictorial Presentation:

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

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); }
