This
 program tells you how to get input from user in a java program. We are 
using Scanner class to get input from user. This program firstly asks 
the user to enter a string and then the string is printed, then an 
integer and entered integer is also printed and finally a float and it 
is also printed on the screen. Scanner class is present in java.util 
package so we import this package in our program. We first create an 
object of Scanner class and then we use the methods of Scanner class. 
Consider the statement 
 
 Scanner a = new Scanner(System.in);  
 
Here Scanner is the class name, a is the name of object, new 
keyword is used to allocate the memory and System.in is the input 
stream. Following methods of Scanner class are used in the program below
 :- 
1) nextInt to input an integer 
2) nextFloat to input a float 
3) nextLine to input a string

 s = in.nextLine();
 System.out.println("You entered string "+s);
 
 System.out.println("Enter an integer");
 a = in.nextInt();
 System.out.println("You entered integer "+a);
 
 System.out.println("Enter a float");
 b = in.nextFloat();
