import java.applet.*;
import java.awt.*;

public class ReadString extends Applet{
	public static void crash() {
		byte[] b = new byte[2];
		b[0]=(byte)0xff;

		ByteArrayInputStream bais = new ByteArrayInputStream(b);
		String s;
		InputStreamReader isr= null;
		try{
		isr = new InputStreamReader(bais,"Unicode");
		}
		catch (java.io.UnsupportedEncodingException e) { e.printStackTrace(); }
		
		BufferedReader in = new BufferedReader( isr   );
		
		try {
			while ( (s = in.readLine()) != null ) {	   System.out.println( s );}
		}

		catch (java.io.IOException e) {	e.printStackTrace(); }
