Java8 new feature: Consumer, Predicate and Supplier
Consumer: The Consumer interface represents an operation that accepts a single input argument and returns no result. It is often used to perform operations such as printing, logging, or modifying objects.
Predicate: The Predicate interface represents a boolean-valued function of one argument. It is often used to test conditions and filter collections of data.
Supplier: The Supplier interface represents a supplier of results. It has no input arguments and returns a result. It is often used to lazily generate or supply values.
These interfaces are part of Java 8's functional programming features and are commonly used with lambda expressions to provide concise and expressive code for manipulating data.
