Java Compared with Other Languages
Java is a new language, but it draws on many years of programming experience with other languages in its choice of features. So a lot can be said in comparing and contrasting Java with other languages. There are at least three pillars necessary to support a universal language for network programming today: portability, speed, and security. Figure 1.2 shows how Java compares to other languages.
Figure 1-2. Programming languages compared
You may have heard that Java is a lot like C or C++, but that’s really not true, except at a superficial level. When you first look at Java code, you’ll see that the basic syntax looks a lot like C or C++. But that’s where the similarities end. Java is by no means a direct descendant of C or a next-generation C++. If you compare language features, you’ll see that Java actually has more in common with languages like Smalltalk and Lisp. In fact, Java’s implementation is about as far from native C as you can imagine.
The surface-level similarities to C and C++ are worth noting, however. Java borrows heavily from C and C++ syntax, so you’ll see lots of familiar language constructs, including an abundance of curly braces and semicolons. Java also subscribes to the C philosophy that a good language should be compact; in other words, it should be sufficiently small and regular so a programmer can hold all the language’s capabilities ...
