Java Program to get input from user

In this tutorial we are gonna see how to accept input from user. We are using Scanner class to get the input. In the below example we are getting input String, integer and a float number. For this we are using following methods:
1) public String nextLine(): For getting input String
2) public int nextInt(): For integer input
3) public float nextFloat(): For float input

Example:

import java.util.Scanner;

class GetInputData
{
  public static void main(String args[])
  {
     int num;
     float fnum;
     String str;
 
     Scanner in = new Scanner(System.in);
 
     //Get input String
     System.out.println("Enter a string: ");
     str = in.nextLine();
     System.out.println("Input String is: "+str);
 
     //Get input Integer
     System.out.println("Enter an integer: ");
     num = in.nextInt();
     System.out.println("Input Integer is: "+num);
 
     //Get input float number
     System.out.println("Enter a float number: ");
     fnum = in.nextFloat();
     System.out.println("Input Float number is: "+fnum); 
  }
}

Output:

Enter a string: 
Chaitanya
Input String is: Chaitanya
Enter an integer: 
27
Input Integer is: 27
Enter a float number: 
12.56
Input Float number is: 12.56
