The cleaning action is a Runnable to be invoked at most once when the object has become phantom reachable unless it has already been explicitly cleaned. Note that the cleaning action must not refer to the object being registered.

What are the 3 most important qualities of written code?

Clarity of code. Clarity of design. Clarity of purpose. You must understand — really understand — what you’re doing at every level.

How do you maintain coding standards?

Focus on code readability

1. Write as few lines as possible.
2. Use appropriate naming conventions.
3. Segment blocks of code in the same section into paragraphs.
4. Use indentation to marks the beginning and end of control structures.
5. Don’t use lengthy functions.
6. Use the DRY (Don’t Repeat Yourself) principle.
7. Avoid Deep Nesting.

How do you ensure code quality in agile?

Some other approaches to ensuring clean quality code in an Agile environment are as follows: Peer review. Behavior-driven development (BDD) Pair Programming….Test-Driven Development (TDD)

1. Coding.
2. Testing (writing unit tests)
3. Design (a form of refactoring)

Which help increases code clarity?

Achieving clarity is about so much more than proper indentation—it takes careful planning from the beginning of the project. While tough to master, abiding by the principles of single responsibility, command-query separation, loose coupling, and high cohesion can improve clarity in our code greatly.

The second benefit of writing a well-tested code is that you can prevent future failure when the small changes to existing code break functionality. When a failure happens you will be informed that you have written something wrong. At first, glance, spending time on writing the unit tests during development looks like extra expenses.

How to measure unit test coverage in Java?

JaCoCo is an open source Java software quality tool for measuring code coverage, showing you what lines in your code have been tested by the unit tests you’ve written. Along with coverage, JaCoCo also reports on the complexity of each method, and tells you how much of the complexity in a method remains untested.
