OrlandoJUG Reading List ::: from JavaSpecialists

Issue 277 - Strings with Zero HashCode

In Java 2, the computational time complexity of String#hashCode() became linear, as it used every character to calculate the hash. Java 3 cached the hash code, so that it would not need to be recalculated every time we called hashCode(), except in the case that the hash code was zero. Java 13 finally fixes that inefficiency with an additional boolean field.

Issue 276 - Serializing Records

Java 14 Records (JEP359) reduce the boiler plate for simple POJOs. In this newsletter we look at what special magic is used to serialize and deserialize these new records.

Issue 275 - EnhancedStream with Dynamic Proxy

In our previous newsletter we enhanced Java 8 Streams by decorating them with an EnhancedStream class. The code had a lot of repetition, which often leads to bugs if written by hand. In this newsletter we use a dynamic proxy to create an EnhancedStream. The resulting code is shorter and more consistent.

Issue 274 - EnhancedStream

Java 8 Streams have a rather narrow-minded view of what makes objects distinct. In this newsletter, we enhance Streams to allow a more flexible approach for deciding uniqueness.

Issue 273 - Truly Public Methods

Class.getMethods() returns all the public methods in this class and the classes in its ancestry. However, we cannot necessarily call these methods, for example if they are declared in a private inner class or a lambda. In this newsletter we attempt to find all truly public methods.
