Program to explain getter and setter

Effective Go Introduction Go is a new language. Although it borrows ideas from existing languages, it has unusual properties that make effective Go programs different in character from programs written in its relatives. On the other hand, thinking about the problem from a Go perspective could produce a successful but quite different program.

In other words, to write Go well, it's important to understand its properties and idioms. It's also important to know the established conventions for programming in Go, such as naming, formatting, program construction, and so on, so that programs you write will be easy for other Go programmers to understand.

This document gives tips for writing clear, idiomatic Go code. It augments the language specificationthe Tour of Goand How to Write Go Codeall of which you should read first. Examples The Go package sources are intended to serve not only as the core library but also as examples of how to use the language.

Moreover, many of the packages contain working, self-contained executable examples you can run directly from the golang. If you have a question about how to approach a problem or how something might be implemented, the documentation, code and examples in the library can provide answers, ideas Program to explain getter and setter background.

Formatting Formatting issues are the most contentious but the least consequential.

People can adapt to different formatting styles but it's better if they don't have to, and less time is devoted to the topic if everyone adheres to the same style. The problem is how to approach this Utopia without a long prescriptive style guide.

With Go we take an unusual approach and let the machine take care of most formatting issues. The gofmt program also available as go fmt, which operates at the package level rather than source file level reads a Go program and emits the source in a standard style of indentation and vertical alignment, retaining and if necessary reformatting comments.

If you want to know how to handle some new layout situation, run gofmt; if the answer doesn't seem right, rearrange your program or file a bug about gofmtdon't work around it. As an example, there's no need to spend time lining up the comments on the fields of a structure.

Gofmt will do that for you. Some formatting details remain.

Indentation We use tabs for indentation and gofmt emits them by default. Use spaces only if you must. Line length Go has no line length limit. Don't worry about overflowing a punched card.

If a line feels too long, wrap it and indent with an extra tab. Parentheses Go needs fewer parentheses than C and Java: Line comments are the norm; block comments appear mostly as package comments, but are useful within an expression or to disable large swaths of code.

The program—and web server—godoc processes Go source files to extract documentation about the contents of the package. Comments that appear before top-level declarations, with no intervening newlines, are extracted along with the declaration to serve as explanatory text for the item.

The nature and style of these comments determines the quality of the documentation godoc produces. Every package should have a package comment, a block comment preceding the package clause.

For multi-file packages, the package comment only needs to be present in one file, and any one will do. The package comment should introduce the package and provide information relevant to the package as a whole.

It will appear first on the godoc page and should set up the detailed documentation that follows. The syntax of the regular expressions accepted is: Comments do not need extra formatting such as banners of stars.

The generated output may not even be presented in a fixed-width font, so don't depend on spacing for alignment—godoc, like gofmt, takes care of that.

One adjustment godoc does do is to display indented text in a fixed-width font, suitable for program snippets.

The package comment for the fmt package uses this to good effect. Depending on the context, godoc might not even reformat comments, so make sure they look good straight up: Inside a package, any comment immediately preceding a top-level declaration serves as a doc comment for that declaration.

Every exported capitalized name in a program should have a doc comment.Object-Oriented Programming Languages. Object-oriented programming (OOP) languages are designed to overcome these problems.

The basic unit of OOP is a class, which encapsulates both the static properties and dynamic operations within a "box", and specifies the public interface for using these boxes. Since classes are well-encapsulated, it is easier to reuse these classes. explanation of getter/setter methods -- what's the difference exactly?

Could you (or anyone else, for that matter) walk me through the code example and explain what's going on regarding the setter and getter methods?
