Oct 25, 2019 · Robust simply means heavy and strong and Java has a lot of facilities for programmers such as memory ...
Here are a few links that discuss what it means to be robust in terms of software: Robust Programming; Robust Definition; Robustness, the forgotten code quality. How to write robust code; If you think there is one universally agreed upon definition of "robust" here, good luck. There can be some synonyms like bomb-proof or idiot-proof.
Jul 23, 2014 · Robust. Quoted from Core Java, Volume I, Fundamentals. "Java is intended for writing programs that must be reliable in a variety of ways. Java puts a lot of emphasis on early checking for possible problems, later dynamic (runtime) checking, and eliminating situations that are error-prone. . . .
Nov 14, 2018 · Hashcode direct quote from Effective Java 2nd Edition Store some constant nonzero value, say, 17, in an int variable called result. For each significant field f in your object (each field taken into account by the equals method, that is), do the following:
5) Keep variable scope as narrow as possible. Instantiate objects near where they are used instead of in a large block at the beginning of a method. You'll potentially shorten the life of the objects and you won't forget about unneeded or reused variables sitting in a huge block at the top of the class or method.
Apr 26, 2011 · 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. answered Apr 26, 2011 at 21:00.
Unfortunately, it's nearly impossible to measure the robustness of an arbitrary program because in order to do that you need to know what that program is supposed to do. If you had a specification, you could write a huge number of tests and then run them against any client as a test. For example, look at the Acid2 browser test.
4. final is a reserved keyword in Java to restrict the user and it can be applied to member variables, methods, class and local variables. Final variables are often declared with the static keyword in Java and are treated as constants. For example: public static final String hello = "Hello";
May 31, 2016 · 20. There are three flavors of Java: ME for mobile, SE for desktops, and EE for enterprise. "Java is portable" refers to the SE version. It means that you can run Java bytecode on any hardware that has a compliant JVM. It doesn't mean that ME is the same as SE is the same as EE. EE has EJBs, but SE and ME don't.
May 25, 2009 · Casting is the process of type conversion, which is in Java very common because its a statically typed language. Some examples: Cast the String "1" to an int, via Integer.parseInt("1") -> no problem. Cast the String "abc" to an int -> raises a ClassCastException.
