Use private for variables that should only be accessible within the class: If you want to prevent access to a variable from outside the class, use the private access modifier. This is the most restrictive access modifier and provides the greatest level of encapsulation.Functional Interface: This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference. @FunctionalInterface public interface Function<T,R>. Represents a function that accepts one argument and produces a result. This is a functional interface whose functional method is apply (Object).Method references were introduced in java 8. Method reference is a special type of lambda expression. It fulfils the purpose of a lambda expression by increasing the readability and to write a neat code. A method reference works in case of functional interfaces. Wherever, we are calling a method of a functional interface with a …The functions which accept functions as the parameter or/and it return functions as the return value is called a higher-order function.
