Immutable objects are important to make your code more robust, especially in days of more parallelization. A builder pattern is used when some of the variables of an immutable class are required and some are op
Java has no multiple inheritance of state indeed. But JDK 8 introducedmultiple inheritance of behaviorthat we can use to avoid the so-called Diamond problem. Let’s look at an example with two classes,AandB, having a methoddoSomething(). When a classCwould inherit from bothAandB, calling ...

Multiple inheritance with default methods: With using default methods you can have classes which have a mixin behavior of many interfaces but you should notice to an important point. If extended interfaces have a common method signature youwill face with a compile time errorregards to there is an...
Unfortunately, the type systems of languages like Java cannot statically enforce full behavioral substitutability, and in fact there are numerous examples of libraries some of whose components are related by inheritance but not substitutable (for example, because they do not implement "optional" ...
