The differences between the programming languages C++ and Java can be traced to their heritage, as they have different design goals.. C++ was designed for systems and applications programming (i.e., infrastructure programming), extending the procedural programming language C, which was designed for efficient execution.
In software development, the programming language Java was historically considered slower than the fastest third-generation typed languages such as C and C++. [1] In contrast to those languages, Java compiles by default to a Java Virtual Machine (JVM) with operations distinct from those of the actual computer hardware.
This comparison of programming languages compares how object-oriented programming languages such as C++, Java, Smalltalk, Object Pascal, Perl, Python, and others manipulate data structures. Object construction and destruction
It has been suggested that Comparison of Java and C++ be merged into this article. ( Discuss ) Proposed since February 2025. Programming languages are used for controlling the behavior of a machine (often a computer ).

The JIT compiler reads the bytecodes in many sections (or in full, rarely) and compiles them dynamically into machine code so the program can run faster. This can be done per-file, per-function or even on any arbitrary code fragment; the code can be compiled when it is about to be executed (hence the name "just-in-time"), and then cached and ...
Java is smaller than C++. Yes, the java libraries are more extensive, but they are not visible if you don't use them; and the libraries that are most commonly used, such as java.lang.Collections are relatively small. The point is it's a lot easier to learn the fundamentals of java than C++ (though both languages take a long time to master).
It is most commonly associated with the act of compiling a higher-level programming language such as C or C++, or an intermediate representation such as Java bytecode or Common Intermediate Language (CIL) code, into native machine code so that the resulting binary file can execute natively, just like a standard native compiler.
