How To Take Input In Java Using Scanner Class

How To Take Input In Java using Scanner Class. Taking Input In any Programming Language Plays An Important role To Take Input From The User And Store In the variable. Today We Will Talk About How to take input in java?

---

To take input from the user in Java using the Scanner class, first, import the Scanner class from the java.util package. Then, create a Scanner object to read input from the standard input stream, usually System.in. Utilize the Scanner’s appropriate methods based on the type of input you expect (e.g., nextInt() for integers, nextDouble() for doubles, nextLine() for strings). Ensure to handle exceptions if necessary and remember to close the Scanner object after use to prevent resource leaks.

For Taking Input In java

There Are Two Ways To Take Input In java

• Using Scanner Class
• Using Buffered Reader

Today We Will Discuss About The Scanner Class.

Firstly We have to import the Scanner Pacakage Form The java.util Pacakage

For Example

import java.util.Scanner;

Then We Have Create A Scanner Class Object In Our Function

For Example

import java.util.Scanner;

public class Main {

  public static void main(String[] args) {
Scanner scanobj= new Scanner(System.in);
  }
}

Then Create A Variable And Take Input Using nextInt();

For Example

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
Scanner scanobj= new Scanner(System.in);
int a=scanobj.nextInt();
// for print 
System.out.println(a);
  }
}

This is How To Take Input In Java Using Scanner Class

How To take a String Input From User In Java?

You Can Take String Input from user in java by using next() method.To take a string input from the user in Java, you can utilize the Scanner class. First, you need to import the Scanner class from the java.util package. Then, create a Scanner object to read input from the standard input stream, typically System.in. Next, use the Scanner’s nextLine() method to read the entire line of text entered by the user. This method captures whitespace characters as well, making it suitable for reading strings containing spaces. Finally, store the input string in a variable for further processing. Here’s a basic example:

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
Scanner scanobj= new Scanner(System.in);
String a=scanobj.next();
// for print 
System.out.println(a);
  }
}
