Flow of Control

Java has all the usual statements for tests and loops: if/else, switch/case,

for, while, and do/while. Multiple statements are grouped with the { and }

characters. Java also supports exceptions to report error conditions (see the

section entitled “Exceptions”).

1. The following example loops through the lines in the input file and

prints them in the output file:

for(String line = reader.readLine();

null != line;

line = reader.readLine())

writer.println(line);
