Is "import.java.io.*" the reason that the objects "InputStream, Reader, and BufferedReader" have actual functions? Like are the methods that determine the abilities of those objects defined in some class called java.io?
package com.codegym.task.task03.task0318;
/*
Plan to conquer the world
*/
import java.io.*;
public class Solution {
public static void main(String[] args) throws Exception {
//write your code here
InputStream inputStream = System.in;
Reader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String age = bufferedReader.readLine(); //Read a string from the keyboard
String name = bufferedReader.readLine(); //Read a string from the keyboard
System.out.println(name + " will take over the word in");
System.out.println(age + " years. Mwa-ha-ha!");
}
}
