Methanol (CH33OH) - permalink - collapse

All > Science > Climate Change

A colorless poisonous liquid with essentially no odor and little taste. It is the simplest alcohol with a boiling point of 64.7 degrees Celsius. In transportation, methanol is used as a vehicle fuel by itself (M100), or blended with gasoline (M85).

All > Technology > Programming > Java

A function defined in a class. See also instance method, class method. Unless specified otherwise, a method is not static.
Sun Microsystems - Cite This Source - This Definition
The part of a class definition that implements some of the behavior of objects of the class. The body of the method contains declarations of local variables and statements to implement the behavior. A method receives input via its arguments, if any, and may return a result if it has not been declared as void.

method overloading - permalink - collapse

All > Technology > Programming > Java

Two or more methods with the same name defined within a class are said to be overloaded. This applies to both constructors and other methods. Overloading applies through a class hierarchy, so a sub class might overload a method defined in one of its super classes. It is important to distinguish between an overloaded method and an overridden method. Overloaded methods must be distinguishable in some way from each other; either by having different numbers of arguments, or by the types of those arguments being different. Overridden methods have identical formal arguments.

method overriding - permalink - collapse

All > Technology > Programming > Java

A method defined in a super class may be overridden by a method of the same name defined in a sub class. The two methods must have the same name and number and types of formal arguments. Any checked exception thrown by the sub class version must match the type of one thrown by the super class version, or be a sub class of such an exception. However, the sub class version does not have to throw any exceptions that are thrown by the super class version. It is important to distinguish between method overriding and method overloading. Overloaded methods have the same names, but differ in their formal arguments. See overriding for breadth, overriding for chaining and overriding for restriction.

All > Technology > Defense

The technique that subjects each operation of a given piece of work to close analysis to eliminate every unnecessary element or operation and to approach the quickest and best method of performing each necessary element or operation. It includes the improvement and standardization of methods, equipment, and working conditions; operator training; the determination of standard times; and occasionally devising and administering various incentive plans.
