Hi sagarika,
Welcome to Javaranch, a friendly place for Java greenhorns
In Java, you can retrieve characters typed on the keyboard by invoked the read() method on the System.in input stream.
For instance, the following program allows you to read three integer primitives from the keyboard:

import java.io.*;
public class GetNumbers {  
    public static void main(String[] args) throws IOException {  
        System.out.println("Type 3 numbers and press Enter after each");
        BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in));
        int x, y, z;
        x = Integer.parseInt(keyboard.readLine());
        y = Integer.parseInt(keyboard.readLine());
        z = Integer.parseInt(keyboard.readLine());
        System.out.println("Numbers are: " +  x + ", " + y + ", " + z);   
    }
}
