Simple class example

import java.io.*;

@SuppressWarnings("unchecked")
public class PrismJS {

	public static Integer test = 0;

	/**
	 * Javadoc style comment
	 *
	 * @param args
	 */
	public static void main(String[] args) {
		// Let's create some variables
		int numArgs = args.length;
		Integer a = 0x1;
		String test = "" + "Hello" + " \"World\"!";
		double dvalue = 1.23;
		int optest = 0;
		optest += 321 - 45 * 1247 / 425 % 123;

		/*
		 * Multiline comment
		 */
		for (int i = 0; i < numArgs; i++) {

As you can notice String keyword is not highlighted because it's not a Java language keyword (cf. Java Language Keywords). The main reason is that String is not a primitive type such as int but a class type like Integer.
