we’ll briefly highlight some differences between the Java platform and other programming environments you may be familiar with.
Java Compared to C language
- Java is object oriented; C is procedural
- Java is portable as class files; C needs to be recompiled.
- Java provides extensive instrumentation as part of the runtime.
- Java has no pointers and no equivalent of pointer arithmetic.
- Java provides automatic memory management via garbage collection.
- Java has no ability to lay out memory at a low level (no structs).
- Java has no preprocessor.
Java Compared to C++ language
- Java has a simplified object model compared to C++.
- Java’s dispatch is virtual by default.
- Java is always pass-by-value (but one of the possibilities for Java’s values areobject references).
- Java does not support full multiple inheritance.
- Java’s generics are less powerful (but also less dangerous) than C++ templates.
- Java has no operator overloading
Java Compared to PHP
- Java is statically typed; PHP is dynamically typed.
- Java has a JIT; PHP does not (but might in version 6).
- Java is a general-purpose language; PHP is rarely found outside of websites.
- Java is multithreaded; PHP is not.
