Doing so involves restricting what a programmer is allowed to do. Or it requires tests, such as checking whether a pointer is null, that
take some extra processing time. Some programmers feel that the sacrifice of
Java Tutorial
power and efficiency is too high a price to pay for the extra security. However, there are many situations where safety and
security are primary considerations. The compiler checks the program code to detect if there are any errors, and the translator detects run-time errors or compile-time errors and keeps the system from crashing. Robust means strong and healthy where robust programming language refers to a strong programming language.
You know, sometimes for a simple concept, you can make a complex definition and explanation. If the user of your application send you many requests about bugs, about state loss, about unintuitive workflows, etc., then there is something wrong with your programming. These all features make java a robust programming language. Java has stood the test of time and remains such a robust programming language. Its efficiency, scalability, and portability have made it a favorite for large-scale enterprise systems.
This website is using a security service to protect itself from online attacks. The action you just performed triggered the security solution. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. A list of the most important features of the Java language is given below. As
programmers, we need to understand why that is true and what can be done about
it.
The better solution would be to isolate the error handling from the application logic. Most cases, a core dump is approriate, at worst it annoys the user or costs a lot of money. What if, say, the module is the Space shuttle realtime reentry calculation system? Any what is robustness answer, no matter how inaccurate, cannot be worse than aborting, which will kill the users. So what to do, if you know the answer might be wrong, go for the 50/50, or abort and go fo the 100% failure. That allows for a NULL state that is neither true nor false.

These error messages allow the user to more easily debug the program. Robust simply means heavy and strong and Java has a lot of facilities for programmers such as memory management, security features, networking features etc. I know that Robust is a Feature of java programming language. But I don’t know what is the exact meaning of it and how to any programmer benefited by it. Therefore, from the above, we know why Java is a robust programming language.
Java’s introduction of lambda expressions, streams and default interfaces allows Java to support both the functional programming model and the object-oriented model at the same time. A is impossible to test without convoluted test harnesses. If you have not tested the code, how do you know it works? If you don’t know it works, then you are not writing robust software. I think they still call that a Catch22 (Great movie, watch it sometime). “Having no such thing as an error” seems ridiculous as well; even Google applications show errors directly to the user instead of swallowing them up silently or somehow considering them as valid state.
- Applications requiring large amounts of compute power can be designed such that compute-intensive sections can be rewritten in native machine code as required and interfaced with the Java platform.
- You know, sometimes for a simple concept, you can make a complex definition and explanation.
- Without the presence of JRE in Java, the JVM would no…
- In general, users perceive that interactive applications respond quickly even though they’re interpreted.
This awkward situation can be prevented using while loop. Using loops we can manipulate its execution according to our requirements and write healthy codes. Suppose you want to find the area and perimeter of a circle. The general approach for a rookie programmer would be to check if the radius is greater than zero.
In conclusion, Java is a secure and robust programming language that is used by millions of developers around the world. Its built-in security features, such as sandboxing and bytecode verification, help to prevent malicious code from being executed. Its robustness is achieved through features such as automatic memory management and exception handling. All of these features combine to make Java an incredibly versatile language that can be used for a wide range of applications.
A program is correct
if it accomplishes the task that it was designed to perform. It is robust if it can handle illegal inputs and other unexpected
situations in a reasonable way. For example, consider a program that is
designed to read some numbers from the user and then print the same numbers in
sorted order. The program is correct if it works for any set of input numbers. It is robust if it can also deal with non-numeric input by, for example,
printing an error message and ignoring the bad input. A non-robust program
might crash or give nonsensical output in the same circumstance.
Java code is compiled by the compiler and converted into bytecode. This bytecode is a platform-independent code because it can be run on multiple platforms, i.e., Write Once and Run Anywhere (WORA). Object-oriented programming (OOPs) is a methodology that simplifies software development and maintenance by providing some rules. For example,
computer software error contributed to the
Northeast Blackout
of 2003, one of the largest power outages in history. In 2006, the Airbus A380 was delayed
by software incompatibility problems, at a cost of perhaps billions of dollars.
