Compiled Java code files are generally smaller than code files in C++ as Java bytecode is usually more compact than native machine code and Java programs are never statically linked. C++ compiling features an added textual preprocessing phase, while Java does not. Thus some users add a preprocessing phase to their build process for better ...
BBC iPlayer was one of four services available at the launch of YouView in July 2012. At launch, the BBC iPlayer app contained options to resume watching recent programmes, access favourites, browse the most popular shows, find similar programmes or more episodes, included integrated search and was the only service to feature HD video.

C compilers do not name mangle symbols in the way that C++ compilers do. [20] Depending on the compiler and architecture, it also may be the case that calling conventions differ between the two languages. For these reasons, for C++ code to call a C function foo(), the C++ code must prototype foo() with extern "C".
For example, C allows implicit conversion from void * to other pointer types but C++ does not (for type safety reasons). Also, C++ defines many new keywords, such as new and class, which may be used as identifiers (for example, variable names) in a C program.
The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A Java platform includes an execution engine (called a virtual machine), a compiler and a set of libraries; there may also be additional servers and alternative libraries that depend on the requirements.

IDLs are usually used to describe data types and interfaces in a language-independent way, for example, between those written in C++ and those written in Java. IDLs are commonly used in remote procedure call software. In these cases the machines at either end of the link may be using different operating systems and computer languages. IDLs ...
In the JNI framework, native functions are implemented in separate .c or .cpp files. (C++ provides a slightly simpler interface with JNI.) When the JVM invokes the function, it passes a JNIEnv pointer, a jobject pointer, and any Java arguments declared by the Java method. For example, the following converts a Java string to a native string:
