How to Read from stdin in Java
Reading from stdin in java looks like in most languages. Standard in is bound to System.in - and must be opened as if it where a file just like in c.
Then you can iterate over the lines like in Ruby - and print it to stdout with System.out.print
import java.util.*;
class Stdin
{
public static void main (String [] args) throws java.io.IOException
{
Scanner input = new Scanner(System.in);
while(input.hasNextLine())
{
System.out.print (input.nextLine()+"\n");
}
}
}
