Java stdIn and stdout  - Practical

 

The most popular way to read input from stdin is by using the Scanner class and specifying the Input Stream as System.in.

 

For example:

 

          Scanner scanner = new Scanner(System.in);

          String myString = scanner.next();

          int myInt = scanner.nextInt();

          scanner.close();

          System.out.println("myString is: " + myString);

          System.out.println("myInt is: " + myInt);

 

The code above creates a Scanner object named and uses it to read a String and an int.

It then closes the Scanner object because there is no more input to read, and prints to stdout using System.out.println(String).

 

So, if our input is:

Hi 5

Our code will print:

myString is: Hi

myInt is: 5

 

Alternatively, you can use the BufferedReader class.

Task
In this challenge, you must read  integers from stdin and then print them to stdout. Each integer must be printed on a new line. To make the problem a little easier, a portion of the code is provided for you in the editor below.

Input Format

There are lines of input, and each line contains a single integer.

Sample Input

42

100

125

Sample Output

42

100

125
