Java Stdin and Stdout I

One 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
