Question

4a. For this exercise, you will use the Scanner Class and the Math Class. Write a program that uses a Scanner object to read in two different numbers. Determine which is the largest and smallest of the two numbers. Print the number that is the largest of the two. Then subtract the smallest number from the largest of the two numbers and print this result. Calculate and print the square this result. Calculate and print the square of the small number. Then print out the largest of the two numbers. See below for sample output.

Type the first number: 10
Type the second number: 60

The largest number is 60.0
60.0 minus 10.0 is 50.0
The square of 50.0 is 2500.0
The square of 10.0 is 100.0
2500.0 is larger than 100.0

Test the program with three sets of data and include the results in this report. Do not concern yourself with controlling the display of the decimal point.

4b. Write a program that uses a Scanner object that asks for your name and your examen, assignment and lab marks. The examen counts for 40%, assignments 40% and labs 20%. The program computes your grade percentage. Test the program with three sets of data and include the results in this report. Do not concern yourself with controlling the display of the decimal point.

Sample output:

Explanation / Answer

4a)

FindLargestAmongTwo.java

import java.util.Scanner;

public class FindLargestAmongTwo {

public static void main(String[] args) {

//Declaring variables

double num1, num2, largest, smallest, res;

/*

* Creating an Scanner class object which is used to get the inputs

* entered by the user

*/

Scanner sc = new Scanner(System.in);

//Getting the first input entered by the user

System.out.print("Type the first number: ");

num1 = sc.nextInt();

//Getting the second input entered by the user

System.out.print("Type the second number: ");

num2 = sc.nextInt();

//finding the largest number

if (num1 > num2) {

largest = num1;

smallest = num2;

} else {

largest = num2;

smallest = num1;

}

//Displaying the output

System.out.println("The largest number is " + largest);

//calculating the difference

res = (largest - smallest);

System.out.println(largest + " minus " + smallest + " is " + res);

//calculating the square of numbers

num1 = Math.pow(res, 2);

num2 = Math.pow(smallest, 2);

//Displaying the output

System.out.println("The square of " + res + " is " + num1);

System.out.println("The square of " + smallest + " is " + num2);

if (num1 > num2)

System.out.println(num1 + " is larger than " + num2);

else

System.out.println(num2 + " is larger than " + num1);

}

}

Output:

Type the first number: 10
Type the second number: 60
The largest number is 60.0
60.0 minus 10.0 is 50.0
The square of 50.0 is 2500.0
The square of 10.0 is 100.0
2500.0 is larger than 100.0

int examen, assignment, lab;

double final_grade;

/*

* Creating an Scanner class object which is used to get the inputs

examen = sc.nextInt();

System.out.print("Please enter your assignment mark:");

assignment = sc.nextInt();

System.out.print("Please enter your lab mark:");
