Lab 5 objectives
The aims of this lab are:
- Learn to use Scanner class
- Use Scanner class to input numbers values and String values
Exercise 1
1. Create an empty project called Exercise1 and save it in the folder
Z:\ICS102\Labs\.Lab5\Exercise1 created earlier.
2. Create a new Java file named Ex1 and add it to the project.
3. Complete the program below to allow you enter your name ,and your Id using
Scanner class and then print what you entered using println method. To obtain the
following Sample output
Enter your Name
Huda Alenzi
Enter your age
12
Your Name is Huda Alenzi
your age is 12.0
//Import Scanner class
import java.util.Scanner;
class Ex1
{ public static void main(String[] args) {
String name;
double age;
//create object keyboard from Scanner class
Scanner keyboard=new Scanner(System.in);
//write prompt input for name
System.out.println("Enter your Name");
// use keyboard to input the value of name
name=keyboard.nextLine();
//write prompt input for age
System.out.println("Enter your age");
// use keyboard to input the value of age
age=keyboard.nextDouble();
//print the value of name what is entered
System.out.println("Your name is"+name);
System.out.println("Your age is"+age);
}}
Exercise 2
1. Create an empty project called Exercise2 and save it in the folder
Z:\ICS102\Labs\.Lab5\Exercise2 created earlier.
2. Create a new Java file named Ex2 and add it to the project.
3. Complete the program below to compute the area for Rectangle based on the
following formula: Area=length*width
Your program should allow you to enter the value for length and width of the
rectangle.
Enter the side of Square
9
The Area of Square is 81.0
//Import Scanner class
import java.util.Scanner;
class Ex2
{public static void main(String [] args)
{// create object key from Scanner class
Scanner key=new Scanner(System.in);
//define variable to store the value of side
double side;
//define variable to store the value of Square’s area
double area;
//write prompt input for side
System.out.println ("Enter the side of Square");
// use object key to input the Side value
side=key.nextDouble();
// compute the area as the above formula area=side*side
area=side*side
// print the value of area using prinln() method
System.out.println("the Area of Square is "+area);}}
