Java 1.5
Java 1.5 is scheduled for release in 2004; as of April 2004, the beta version is available. Like all versions of Java, it can be downloaded at no charge from Sun's website.
This version of Java, codenamed "Tiger", contains long-awaited syntax shortcuts such as foreach and autoboxing.
For each
The new for loop syntax is illustrated in the following source code snippet:
List<String> curses = new ArrayList<String>();
curses.add("foo"); curses.add("bar"); curses.add("snafu");
// The old iterator... String result = "";
for (Iterator it = curses.iterator(); it.hasNext(); ) {
result += (String)it.next(); }
assert result.equals("foobarsnafu");
// The new Java 1.5 iterator...
result = ""; for (String s: curses) { result += s; } // fits neatly on one line!
assert result.equals("foobarsnafu");
