The runtime overhead of added instrumentation is small (5–20%) and the bytecode instrumentor itself is very fast (mostly limited by file I/O speed). Memory overhead is a few hundred bytes per Java class. EMMA is 100% pure Java, has no external library dependencies, and works in any Java 2 JVM (even 1.2.x).
In object oriented programming, objects provide a layer which can be used to separate internal from external code and implement abstraction and encapsulation. External code can only use an object by calling a specific instance method with a certain set of input parameters, reading an instance variable, or writing to an instance variable.
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile.

In software engineering, code coverage, also called test coverage, is a percentage measure of the degree to which the source code of a program is executed when a particular test suite is run. A program with high code coverage has more of its source code executed during testing, which suggests it has a lower chance of containing undetected ...
For n = 1 million, X n is roughly 0.9999, but for n = 10 billion X n is roughly 0.53 and for n = 100 billion it is roughly 0.0017. As n approaches infinity, the probability X n approaches zero; that is, by making n large enough, X n can be made as small as is desired, [3] and the chance of typing banana approaches 100%.
In computer programming, cohesion refers to the degree to which the elements inside a module belong together. [1] In one sense, it is a measure of the strength of relationship between the methods and data of a class and some unifying purpose or concept served by that class.
Person typing on a laptop keyboard Video of typing on a notebook computer keyboard. Typing is the process of writing or inputting text by pressing keys on a typewriter, computer keyboard, mobile phone, or calculator. It can be distinguished from other means of text input, such as handwriting and speech recognition. Text can be in the form of ...
The 1024 points in the range U+D800 – U+DBFF are known as high-surrogate code points, and code points in the range U+DC00 – U+DFFF (1024 code points) are known as low-surrogate code points. A high-surrogate code point followed by a low-surrogate code point forms a surrogate pair in UTF-16 in order to represent code points greater than U+FFFF .
