Wrapping of Streams

A program that demonstrates the wrapping of streams and readers

import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.IOException;
import java.util.Scanner;
import java.util.NoSuchElementException;
 class MaxTest
 {
 public static void main( String [ ] args )
 {
 BufferedReader in = new BufferedReader( new
 InputStreamReader( System.in ) );

 System.out.println( "Enter 2 ints on one line: " );
 try
 {
 String oneLine = in.readLine( );
 if( oneLine == null )
 return;
 Scanner str = new Scanner( oneLine );

 int x = str.nextInt( );
 int y = str.nextInt( );

 System.out.println( "Max: " + Math.max( x, y ) );
 }
 catch( IOException e )
 { System.err.println( "Unexpected I/O error" ); }
 catch( NoSuchElementException e )
 { System.err.println( "Error: need two ints" ); }
 }
 }
