Chapter 3.6, Problem 3.6.4CP

a.

Explanation of Solution

Program code:

//Main class

class Main

{

//Main method

public static void main(String[] args)

  {

//Declare the variable

    int number = 14;

//int number = 15;

//int number = 30;

   //Check if the number is even

    if(number % 2 == 0)

        //Print the statement

        System.out.println(number + " is even");

    //Check if the number is multiple of 5

    if(number % 5 == 0)

        //Print the statement

System.out.println(number + " is multiple of 5");

  }

}

Output:

Here, whatever the number is given both the “if” condition is checked.

If the value “14” is assigned to the variable “number”:

“14 is even” gets printed because, “14” is an even number and the 1^st “if” condition gets executed...

b.

Explanation of Solution

Program code:

//Main class

class Main

{

//Main method

public static void main(String[] args)

  {

//Declare the variable

    int number = 14;

//int number = 15;

//int number = 30;

   //Check if the number is even

    if(number % 2 == 0)

        //Print the statement

        System.out.println(number + " is even");

    //Check if the number is multiple of 5

    else if(number % 5 == 0)

        //Print the statement

System.out.println(number + " is multiple of 5");

  }

}

Output:

Here, if the “if” statement is true, then “else if” part does not gets executed...
