How can I take the input from user in java?

Answer 1

There are 3 classes in java with which you can take input from user:

1.) Scanner Class.
2.) Buffered Reader class.
3.) Console class.

Syntax of all these 3 classes is different but i prefer you to use Buffered Reader class because it is convenient and flexible enough to read whole line with white spaces.

import java.io.IOException;
import java.io.BufferedReader;

class Abc{

public static void main(String arg[])throws IOException{

BufferedReader br= new BufferedReader(new InputStreamReader(System.in));

String name;
System.out.println(" Enter your name: ");
name=br.readLine();

System.out.println(" Welcome Mr. "+name);

}
}
