In the cases where this effort will involve Applets, Servlets, orJavaServer Pages, the programmer will be faced with a rathercomplex object-oriented programming language to understand - Java. Obtaining a level of proficiency with Java involves aconsiderable investment in time and effort. However, ...
Scanner and parser for a programming language are responsible for discovering the syntactic structure of a program 30 Scanning ? Will create a simple “calculator language” with input, output, variables, and assignment extending the grammar shown in Example 2.4 and 2.8 ? Tokens for the simple ...
The first character must be a valid first character (letter, $, _) in an identifier of the Java programming language, hereafter in this chapter called simply “Java”. Each subsequent character in the sequence must be a valid nonfirst character (letter, digit, $, _) in a Java identifier...

Determined novices with no prior programming experience may also find it useful. If you already know Java, you should find it a useful language reference. The chapter includes some comparisons of Java to C and C++ for the benefit of programmers coming from those languages....
An interface defines the methods, a deriving class (subclass) should use. But the implementation of the methods is totally up to the subclass. What is Next? The next section explains about Objects and classes in Java programming. At the end of the session, you will be able to get a clea...
The EL has a comprehensive set of operators as you might expect. We will explore these in this section. As you'll see, many of them are the same as those found in the Java Programming language. The main difference, however, is that for many operators there is a textual equivalent. The...
