| - | : //The Java® programming language is a general-purpose, concurrent, [[dido:public:ra:xapend:xapend.a_glossary:c:class|class]]-based, object-oriented language. It is designed to be simple enough that many programmers can achieve fluency in the language. The Java programming language is related to C and C++ but is organized rather differently, with a number of aspects of C and C++ omitted and a few ideas from other languages included. It is intended to be a production language, not a research language, and so, as C. A. R. Hoare suggested in his classic paper on language design, the design has avoided including new and untested features.// | + | : //The Java® [[dido:public:ra:xapend:xapend.a_glossary:p:programlang|programming language]] is a general-purpose, concurrent, [[dido:public:ra:xapend:xapend.a_glossary:c:class|class]]-based, object-oriented language.

| : //The Java programming language is strongly and statically typed. This specification clearly distinguishes between the compile-time errors that can and must be detected at compile time, and those that occur at run time. Compile time normally consists of translating programs into a machine-independent byte code representation. Run-time activities include loading and linking of the classes needed to execute a program, optional machine code generation and dynamic optimization of the program, and actual program execution.// | : //The Java programming language is strongly and statically typed.

| : //The Java programming language is a relatively high-level language, in that details of the machine representation are not available through the language. It includes automatic storage management, typically using a garbage collector, to avoid the safety problems of explicit deallocation (as in C's free or C++'s delete). High-[[dido:public:ra:xapend:xapend.a_glossary:p:performance|performance]] garbage-collected implementations can have bounded pauses to support systems programming and real-time applications. The language does not include any unsafe constructs, such as array accesses without index checking, since such unsafe constructs would cause a program to behave in an unspecified way.// | : //The Java programming language is a relatively high-level language, in that details of the machine representation are not available through the language.
