Answer:
import java.util.Scanner;
public class TestClock {
public static void main(String[] args) {
Scanner in = new Scanner (System.in);
System.out.print("Enter favorite color:");
String word1 = in.next();
System.out.print("Enter pet's name:");
String word2 = in.next();
System.out.print("Enter a number:");
int num = in.nextInt();
System.out.println("you entered: "+word1+" "+word2+" "+num);
}
}
Explanation:
Using Java Programming language
- Import the Scanner class
- create an object of the scanner class
- Prompt user to enter the values for the variables (word1, word2, num)
- Use String concatenation in System.out.println to display the output as required by the question.

Answer:
The correct option is D: Control Bus
Explanation:
A control bus is usually used by the Central Processing Unit to communicate with all the devices that are connected or contained within a computer. This connections are usually done via physical connections such as printed circuits or cables. It is also called a Computer bus and helps in coordinating activities between the connected devices.

Answer:
showProduct(int,double)
for example: showProduct(10,10.5) is the correct answer even showProduct(10,10.0) is also correct but showProduct(10.0,10.5) or showProduct(10,10) or showProduct(10.0,10) are wrong calls.
Explanation:
The code is
- <em>public static void showProduct (int num1, double num2){</em>
- <em> int product;</em>
- <em> product = num1*(int)num2;</em>
- <em> System.out.println("The product is "+product);</em>
- <em> }</em>
showProduct is function which asks for two arguments whenever it is called, first one is integer and second one is of type double which is nothing but decimal point numbers. Generally, in programming languages, 10 is treated as integer but 10.0 is treated as decimal point number, but in real life they are same.
If showProduct( 10,10.0) is called the output will be 'The product is 100'.
Strange fact is that, if you enter showProduct(10,10.5) the output will remain same as 'The product is 100'. This happens because in the 3rd line of code,which is <em>product=num1*(int)num2</em>, (int) is placed before num2 which makes num2 as of type integer, which means whatever the value of num2 two is given, numbers after decimal is erased and only the integer part is used there.
This is necessary in JAVA and many other programming languages as you <u>cannot</u><u> multiply two different datatypes</u> (here one is int and another is double). Either both of them should be of type int or both should be of type double.
