How to take input from user in java

In this tutorial, we are gonna see how to accept input from a 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 the 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
