What is defensive programming in Java?
Defensive programming is an approach to programming that attempts to ensure that software continues to function in adverse or unforeseen circumstances. In this course, you’ll learn how to code defensively to manage and protect data.

What are the coding guidelines in Java?
Top 10 Java Coding Standards
- Variable scopes, readability and lambda expression. In Java, every declared variable has a scope.
- class fields.
- Treatment of method arguments as local variables.
- Boxing and Unboxing.
- Interfaces.
- String instruments.
- Naming conventions.
- Standard Libraries.
What is meant by defensive programming?
Defensive programming is a form of defensive design intended to ensure the continued function of a piece of software in unforeseen circumstances. Making the software behave in a predictable way despite unexpected user input or actions.
How would you apply defensive coding practices?
There are no surprises.
- Substitution of logical statements by methods controlled by tables. Let’s build better software with decision tables instead of if-else.
- Better software without If-Else. 5 ways to replace If-Else.
- Stop using If-Else statements. Write clean and maintainable code without if-else.
- Do not use database generated IDs.
What are some defensive programming strategies?
The authors recommend developers follow these five defensive programming techniques: design by contract, respect that dead programs don’t tell lies, implement assertive programming, learn to balance resources, and don’t fall for the headlights.
Is defensive programming good or bad?
Defensive Programming: Preconditions This technique is designed to ensure code correctness and reduce the number of bugs. Writing code like this is good practice as it allows you to react quickly to any unexpected situation, thus adhering to the fail fast principle.
What are the coding rules?
The coding rules and guidelines ensure that the software:
- Safe: It can be used without causing harm.
- Secure: cannot be hacked.
- Reliable: Works as it should, every time.
- Testable: It can be tested at the code level.
- Maintainable: It can be maintained, even as your code base grows.
What is the goal of the standard coding style?
Purpose of having coding standards: A coding standard gives code written by different engineers a uniform appearance. It improves the readability and maintainability of the code and also reduces the complexity. It helps in code reusability and helps to catch bugs easily.
What is an example of defensive programming?
Defensive programming is the practice of writing software to allow continued operation after and while experiencing unplanned problems. A simple example is to check for NULL after calling malloc() and make sure the program correctly handles the case.
What are the coding techniques?
Top 7 Programming Techniques That Would Come in Handy
- Variables. Variables can be considered as the most essential programming techniques.
- Repetition or Loops. “For” is the most common type of repetition.
- Decisions or Selection.
- arrays.
- modular arithmetic.
- Text manipulation.
- Random numbers and scale.
Which of the following is not a type of programming language?
The answer to your query is option {c} LASER. Because LASER is not a programming language for computers. Like all other options, they are examples of true programming languages like BASIC, FORTRAN, PASCAL, along with C, C++, JAVA, etc.
What are the general circumstances in which injection attacks are found?
What are the general circumstances in which injection attacks are found? faults related to invalid handling of input data. specifically, when input data may accidentally or deliberately influence the flow of program execution. command injection, sql injection, code injection, remote code injection.
What are the basics of defensive programming in Java?
In this course, you will explore the fundamentals of defensive programming in Java, including how to use assertions and annotations, and how to use classes, types, methods, and program flow control safely. You will also learn how to handle exceptions correctly, how to manage resources, and how to safely terminate a program.

Who is responsible for an illegal argument exception in Java?
Essentially, the responsibility rests with the caller. However, if for example you are providing a third party library that is distributed then you need to validate node for nulls etc. An illegalArugementException is the Java standard, but it is also a RunTimeException.
