The compiler, which confirms that there are no program errors, safeguards the system from crashes. One of the main reasons you should learn Java is because it is an incredibly versatile language. You can use Java to build applications for almost any platform, including desktop, mobile, and web. Millions of developers use Java to create everything from desktop programs to sophisticated web apps. This makes it a useful skill to have for anybody looking to work in tech. In addition to Java’s multi-threading capabilities, Java has an extremely powerful concurrency API that allows developers to create programs that take advantage of multicore computers in a multitude of ways.
You benefit from much faster development cycles–prototyping, experimentation, and rapid development are the normal case, versus the traditional heavyweight compile, link, and test cycles. Primary characteristics of the Java programming language include a
simple language that can be programmed without extensive programmer training while being attuned to current software practices. The fundamental concepts of Java technology are grasped quickly; programmers can be productive from the very beginning. The design requirements of the Java
programming language are driven by the nature of the computing environments in which software must be deployed. Judging by their name it is an entity representing some exceptional situation that happens inside your program. We might encounter certain situations in which the operations that we perform might not be legal, which means that it might be unacceptable mathematically or logically when working with a wide variety of values.
Object-oriented means we organize our software as a combination of different types of objects that incorporate both data and behavior. Therefore, we are giving you some information what is robustness about robust programming languages. Robustness is the capacity of a computer system to handle the errors during execution and manage the incorrect input of data.
There are two types of platforms software-based and hardware-based. The Java Virtual Machine automatically removes objects that appear to no longer be recognized by a Java application through the rubbish collection. In other statements, it is a method of disposing of unuseful objects. The managed runtime provided by the JVM allows Java programs to be portable.
Contrast this with Python, a language where the limitations of the garbage collector prevent a multithreaded application to move beyond a single processor. Java’s security and robustness is as important today as it ever has been. This benefit of Java continues to give network administrators and home users confidence that the programs they run are less likely to install malware or be subject to a malicious attack. So not only is Java still relevant in terms of OOA&D, but it has evolved to support functional programming, which is just as important today as support for object-oriented programming.

In the job market, Java proficiency is also in high demand. Many businesses are looking for Java-savvy developers to create and maintain their software. The average annual income for a Java developer in the US is over $100,000, making it a profitable career choice, according to Indeed. The original Java whitepaper promised that Java would be interpreted and dynamic to eliminate the compile-link-load-test-crash-debug cycle that C and C++ developers suffered through at the time. Java programs can’t run as fast as a close-to-the-metal binary file generated by Rust or C++, but it comes very close. That minor performance hit is a minor price to pay when you take into account all 7 benefits of Java.
What is Robust in java [closed]
Any attempt to use a null value as if it were a pointer
to an actual object will be detected by the system. In some other languages,
again, it’s up to the programmer to avoid such null pointer errors. In my first
Macintosh computer, a long time ago, a null pointer was actually implemented as if it
were a pointer to memory location zero. A program could use a null pointer to
change values stored in memory near location zero. Unfortunately, the Macintosh
- If the user enters a number less then or equal to zero multiple times then we need to compile our code again and again since the program will print enter non zero positive number and finish its execution.
- Rather, it will suspend or terminate the program and prevent this from causing any damage to the system.
- In addition to sandboxing, Java also has a number of other security features that help to prevent common security vulnerabilities.
- Java supports dynamic compilation and automatic memory management (garbage collection).
stored important system data in those locations. Changing that data could cause
the whole system to crash, a consequence more severe than a single failed
Thus, when making a more redundant system, the system also becomes more complex and developers must consider balancing redundancy with complexity. Java also has a robust exception-handling system that allows developers to gracefully handle errors and exceptions. When an error or exception occurs, Java provides a detailed stack trace that can be used to identify the source of the problem.
It is an excellent thing when you want to mix and match dependencies when updating a design. Sometimes dependencies can get tricky, but this hardly ever happens. Compare this to Ruby where gems versioning hell breaks loose as a rule every time you want to update a project’s dependencies.
automatic garbage collector runs as a low-priority background thread, ensuring a high probability that memory is available when required, leading to better performance. 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. In general, users perceive that interactive applications respond quickly even though they’re interpreted. Memory leak
Another type of error that cannot occur in Java is a memory leak. In Java,
once there are no longer any pointers that refer to an object, that object is
“garbage collected” so that the memory that it occupied can be reused.
