This RTE allows Java programmers to design programs on one platform, but to be able to run them on many. This means a programmer can concentrate on program development rather than understanding how different computer systems actually work.Ī common RTE is the Java Runtime Environment.

A virtual machine is an emulation of a computer system that can be made to run on a different computer. It works on different platforms, meaning a program can be developed on different systems and still work.Īn RTE creates a virtual machine in order to run a program. Runtime environmentsĪ runtime environment (RTE) is special software that allows a program to run on a computer, even if it is not designed to run on it. However, they do not usually help to identify errors. These tools help to improve the readability of code. Editors are often fairly simple, but usually offer facilities such as: EditorsĮditors are software which allow programmers to write and edit code. To read more about maintainability, see the producing robust programs study guide. IDEs help a programmer to produce error-free, maintainable code.
