According to my view Combining System.in and java.util.Scanner provides a best way to read user input that can run inside an IDE. It also provides a way to read different data types.  For reading string input:  import java.util.Scanner; public class Test { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("What is your favorite color? "); String name = scanner.next(); System.out.println("Your favorite color is: " + name); } } Now you can use for different types of input like For reading Byte : byte number = scanner.nextByte(); Integer : int number = scanner.nextInt(); Double : double number = scanner.nextDouble(); Boolean : boolean bool = scanner.nextBoolean(); Short : short number = scanner.nextShort(); Long : long number = scanner.nextLong(); Float : float number = scanner.nextFloat(); There are also different ways to read input from user like BufferedReader and InputStreamReader

Yes i guess it's much more easier to implement.

first import java.util.Scanner; on the tip of the class secondly create the object inside main or in declaration area in ur class: Scanner in = new Scanner(System.in); now if ur input variable is already declared do this. if ur input is integer: int a = in.nextInt(); if ur input is string or char: char a = in.nextLine(); String a = in.nextLine();
