New page

Reading a file into a string in Ruby is as simple as:

<geshi lang="ruby">
File.new('foo.txt').read
</geshi>

Unfortunately, Java has no simple method to do the same bundled with the JDK. Here's the equivalent Java function:
<geshi lang="java">
public String readFile(File file) throws IOException {
BufferedReader br = new BufferedReader(new FileReader(file));
String line;
StringBuilder result = new StringBuilder();
while ((line = br.readLine()) != null) {
result.append(line);
result.append("\n");
}
br.close();
return result.toString();
}
</geshi>
