Java templates are syntactic sugar to aid in compile-time type checking. C++ templates are a Turing-complete code generation system.

Its interface looks like Microsoft Visual Studio and is used with JDK . Deep and rich API for managing projects, tasks, dependency artifacts etc. Support for Android is lacking a little bit as some of the android projects doesn’t follow the maven project. All builds and dependencies are combined in the Maven spec and forced in the source code with the developer code.

Fundamentally, the semantics of Java dictate that it is a slower language than download C++. In Java, you can only operate on generic objects through run-time inheritance.

In C++, templates have literally zero overhead- something Java can’t match. This means that all generic code in Java is inherently slower than a generic equivalent in C++. Where a C++ compiler can look up a member variable in constant time, a Java run-time has to follow another pointer. The more accesses you do, the slower this is gonna get, and there’s nothing the JIT can do about it. Ultimately, my personal experience is that Java could be about half the speed of C++, on average. However, there’s realistically no way to back up any performance statements without an extremely comprehensive benchmark suite, because of the fundamentally different algorithms involved.

I should add that some (all?) of those disadvantages are seen by many as advantages of Java. The verbosity situation is slowly improving a little, but you certainly don’t see Java winning code golf contests very often, and in ordinary code it tends to use quite a lot of code as well. I suspect there are at least a few who see it as more readable and understandable, so it can probably be seen as an advantage as well. At the same time, C++ is already well established, and I doubt most game studios see enough advantage to bother switching to Java. I’d say that managed is really a separate category on it’s own, although I’d say it’s definitely more like an interpreted language than a compiled language. More importantly, there pretty much only are two major managed systems, the JVM and the CLR, and when you say "managed" it’s sufficiently explicit.

It’s worth noting that a major part of the speed of an implementation, it’s memory allocator, are very different algorithms in Java and C++. This means that it’s very hard to write a benchmark that might meaningfully compare them. Some memory allocation patterns run much faster with a GC, some run much faster with a native allocator. Absolutely any language is inferior "in one way or another". Java looks a lot different when you view it as a framework / platform instead of just a language. Maybe the problem is that the name is essentially "Java" for both. Software Engineering Stack Exchange is a question and answer site for professionals, academics, and students working within the systems development life cycle.

Firstly some context, my C++ is very rusty, so most of my experiences with Java relate to my more recent experience with C#, which is a much more apples to apples comparison anyway. @MichaelBorgwardt You may want to mention that the speed need time because most JVM’s need to start from scratch every time. Anything where you work with large datasets and C++ can be optimized to access them in a cache-friendly manner.

• An object is a self-contained entity that contains attributes and behavior, and nothing more.
• This combination can occur at vastly different levels of granularity, from fine-grained objects such as a Number, to coarse-grained objects, such as a FundsTransfer service in a large banking application.
• Instead of having a data structure with fields and passing that structure around to all of the program logic that acts on it , in an object-oriented language, data and program logic are combined.
• Each tabbed window shown in Figure 1 is a view for the Java perspective.
• Package Explorer and Outline are two particularly useful views.
