Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on interfaces. It manages to add many of the features of functional languages wit...
These utilities include null-safe or null-tolerant methods for computing the hash code of an object, returning a string for an object, comparing two objects, and checking if indexes or sub-range values are out-of-bounds. requireNonNullElse returns the first argument if i...
Bounds checking is a procedure that's used to ensure that a variable conforms with the bounds of an array. The main situations in...
IndexOutOfRangeException: Index was outside the bounds of the array." which makes no sense to me. Getting Error “The remote server returned an error: (403) Forbidden” when screen scraping using HttpWebRequest.GetResponse() Getting error when trying to send email Getting error while Updating...
If we use any uninitialized array in C program, compiler will not generate any compilation and execution error i.e. program will compile and execute properly.If the array is uninitialized while declaring and even after the declaration if you do not initialize then, you may get unpredictable ...
Java Virtual Machine interprets the byte code into the machine code depending upon the underlying operating system and hardware combination. It is responsible for all the things like garbage collection, array bounds checking, etc… JVM is platform dependent. The JVM is called “virtual” because...

Java has always suffered relative to C/C++ in matrix multiplication because Java does range checks on every array access (set or get). With some clever static and run-time analysis, we are able to eliminate most of the array bounds checks. They show on matrix benchmarks that this one imp...
A checked exception in Java represents a predictable, erroneous situation that can occur even if a software library is used as intended. For example, if a developer tries to access a file, the Java IO library forces them to deal with the checkedFileNotFoundException. The developers of the Ja...
