Robust meaning in java

Among the features of Robustness means that which is strong, powerful and not effected by others. But how is java strong and powerful, In what sense? Secure means safe and protected. Is this means that the bytecode generated by the java compiler is safe and protected from outside attacks , if we change anything in the bytecode then it wont run? How far I am correct? carox kaur wrote:Among the features of java, it is said that java is robust and secure. The reasons are not clear to me, why it is said so. Positive epithets like robust and secure are often used to attach a good feeling to a product. They don't necessarily correspond to any specific property of the product. In short, more often than not, such words are just marketing bullshit. Study the security flaws in applications written in other languages that frequently get located and published. You will find all sorts of causes that Java simply does not allow - such as buffer over-runs. Look at the history of the design decisions - such things as immutable Strings and array bounds checking are in the language because of security flaws found in earlier languages. Bill

Java is a popular programming language used by developers worldwide to create powerful and scalable applications that can run on a range of platforms. It was introduced by Sun Microsystems in 1995. The Java Runtime Environment (JRE), which is required to run Java applications, is an essential component of the Java platform. This article is designed as a guide for people who want to know what JRE in Java is, what the components of JRE in Java are, and how JRE in Java works. What is JRE in Java? JRE in Java stands for Java Runtime Environment, which is a software package that provides the necessary components to run Java applications. It includes the Java Virtual Machine (JVM), libraries, and other components that are required for executing Java code. The JRE in Java is essential for running applications because it provides the necessary runtime environment for the applications to execute. Without the JRE, Java code would not be able to run on different platforms, making it much less useful as a programming language. The JRE in Java ensures that applications can be deployed on any platform without having to worry about compatibility issues. Why JRE in Java is Important? The JRE is important because it is the foundation for executing Java applications on different platforms. Java code is first compiled into bytecode, which is then executed by the JVM(Java Virtual Machine) with the help of the JRE(Java Runtime Environment). Without the presence of JRE in Java, the JVM would no...

Robustness testing is a quality assurance methodology focussed on testing the robustness of the software and helps in removing the reliability of the software by finding the corner cases by inputting the data that mimics the extreme environmental conditions to determine whether or not the system is robust enough to deliver the required functionality to the user. What is Robustness in Software testing? Robustness is a measure of how well a software system can cope with invalid inputs or unexpected user interactions. A robust system is one that continues to function correctly even in the face of unexpected or invalid inputs. A software system that is robust is able to handle errors and unexpected inputs gracefully, without crashing or producing incorrect results. It is also able to adapt to changes in its operating environment, such as changes in the operating system, hardware, or other software components. • Robustness is an important quality for any software system, but it is especially important for systems that are safety-critical or mission-critical. • For these systems, a failure could have serious consequences, so it is essential that they be able to handle any unexpected inputs or conditions gracefully. What is Robustness Testing? Robustness testing is a type of testing that is performed to assess the ability of a system or component to function correctly when it is subjected to invalid or unexpected inputs, or when it is operating outside of its specified operating ...

Java provides many types of operators which can be used according to the need. They are classified based on the functionality they provide. In this article, we will learn about Java Operators and learn all their types. What are the Java Operators? Operators in Java are the symbols used for performing specific operations in Java. Operators make tasks like addition, multiplication, etc which look easy although the implementation of these tasks is quite complex. • – : Unary minus, used for negating the values. • + : Unary plus indicates the positive value (numbers are positive without this, however). It performs an automatic conversion to int when the type of its operand is the byte, char, or short. This is called unary numeric promotion. • ++ : Increment operator, used for incrementing the value by 1. There are two varieties of increment operators. • Post-Increment: Value is first used for computing the result and then incremented. • Pre-Increment: Value is incremented first, and then the result is computed. • ––: Decrement operator, used for decrementing the value by 1. There are two varieties of decrement operators. • Post-decrement: Value is first used for computing the result and then decremented. • Pre-Decrement: The value is decremented first, and then the result is computed. • ! : Logical not operator, used for inverting a boolean value. Example: Output Postincrement : 10 Preincrement : 12 Postdecrement : 10 Predecrement : 8 3. Assignment Operator ‘=’ Assignment opera...

Take a look at this Basically they're saying that in addition to running on multiple environments (because of being interpreted within the JVM), it also runs the same regardless of environment. The former is what makes it portable, the latter is what makes it architecture-neutral. For example, the size of an int does not vary based on platform; it's established by the JVM. A portable C program: #include #include int main(void) You can take that C program and compile it on any machine with a C compiler and have it work (assuming it supports printf... I am guessing some things out there may not). If you compile it on Windows and try to run that binary on a Mac it won't work. The same sort of program written in Java will also compile on any machine with a Java compiler installed, but the resulting .class file will also run on any machine with a Java VM. That is the architectural neutral part. So, portable is a source code idea, while architectural neutral is an executable idea. Looking around I found another book that describes the difference between the two. For architecture neutral the compiler will generate an architecture-neutral object file meaning that compiled Java code (bytecode) can run on many processors given the presence of a Java runtime. For portable it means there are are no implementation-dependent aspects of the specification. For instance in C++ an int can be 16-bit, or 32 bit depending on who is implementing the specification where as in Java an int is a...

The inventors of Java wanted to design a language which could offer solutions to some of the problems encountered in modern programming. They wanted the language to be not only reliable, portable and distributed but also simple, compact and interactive. The authors of Java have written an influential White Paper that explains the features of java by all of the following buzzwords: • Simple • Object Oriented • Plat...
