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 optional. But this leads to a massive constructor explosion, at least in Java. Today ...
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 you will face with a compile time error regards to there ...
