Code Snippet

We split up the Java text into an array of string tokens, using the following delimiter tokens, which include Java keywords to be highlighted.

public class QHyperJavaProcessor {
    static final String[] keywords = new String[] {
        "package", "import",
        "static", "final", "abstract", "synchronized", "transient",
        "default",
        "class", "interface", "@interface", "enum",
        "extends", "implements",
        "public", "private", "protected",
        "true", "false", "null",
        "instanceof",
        "void", "boolean", "int", "char", "long",
        "throws", "throw", "try", "catch", "finally",
        "new", "this", "super",
        "if", "else", "for", "while",
        "continue", "break",
        "return"
    };
    ...
}
