while

■ A while loop can appear all on one line. i.e.

while ( i < x && a = b ) i++; works.

■ Infinite loops. This code creates an infinite loop: while (true) { }

If you use it, you typically break out of the loop by catching some exception. i.e. catching an EOF exception while reading a file

import java.io.*;

try {

DataInputStream dis = new DataInputStream( new BufferedInputStream( new FileInputStream( "input.file")));

while(true) System.out.print( (char) dis.readByte( ) );

}

catch (EOFException eof) { System.out.println(eof); }

catch (IOException io) { }
