Destroy () method, is Called to allow your servlet to clean up any resources

destroy. Called by the servlet container to indicate to a servlet that the servlet is being taken out of service. This method is only called once all threads within the servlet's service method have exited or after a timeout period has passed.

destroy() is a lifecycle method called by the Servlet container when unloading a specific instance of the Servlet. Similarly, the container will call service() when there's a client requesting the Servlet. ... Short answer: Yes, as service() is a method like any other. Long answer: You can, but it doesn't make sense.

A servlet life cycle can be defined as the entire process from its creation till the destruction. The following are the paths followed by a servlet. The servlet is initialized by calling the init() method. ... Finally, servlet is garbage collected by the garbage collector of the JVM.

the service() method can be called any number of times during servlet life cycle. As long as servlet is not destroyed, for each client request the service() method is invoked.

When a computer or other device is not turned on or connected to other devices, it is said to be "offline." 

Systems overview can be prescribed by data flow diagrams statements is true

Flow diagrams in general are usually designed using simple symbols such as a rectangle, an oval or a circle depicting a processes, data stored or an external entity, and arrows are generally used to depict the data flow from one step to another. A DFD usually comprises of four components.

A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system, modelling its process aspects. A DFD is often used as a preliminary step to create an overview of the system without going into great detail, which can later be elaborated.

The difference between a data flow diagram (DFD) and a flow chart (FC) are that a data flow diagram typically describes the data flow within a system and the flow chart usually describes the detailed logic of a business process. Data Flow and Flow Chart differ in processes, flow, and timing.

The term flow diagram is also used as synonym of the flowchart, and sometimes as counterpart of the flowchart.There are numerous types of flow diagram. System Flow Diagram is basically a graphical and sequential representation of the major steps involved in a systematic process.

Structured English to communicate logic of a program is a pseudo code

Pseudocode is an informal high-level description of the operating principle of a computer program or other algorithm. It uses the structural conventions of a normal programming language, but is intended for human reading rather than machine reading.

Pseudocode (pronounced SOO-doh-kohd) is a detailed yet readable description of what a computer program or algorithm must do, expressed in a formally-styled natural language rather than in a programming language. Pseudocode is sometimes used as a detailed step in the process of developing a program.

An algorithm is a systematic logical approach used to solve problems in a computer while Pseudocode is the statement in plain English which may be translated later into a programming language (program). ... You can base your pseudo code on an algorithm. This contains transferable steps to implement.

Flowchart is usually a graphical representation, like this: where as pseudo-code is something written in a language (for example English) like this: Note that they both show the step by step procedure for solving a problem. One is graphical while one is text based.

Disaster Recovery Plan involves a set of policies, tools and procedures to enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster. It is an essential part of a Business Continuity Plan.
