Java 8 features - class 15- BiPredicate and BiFunction interfaces explained in detail

You can learn Java with me as the Java Programming language is being made easily. It would take a period of minimum three months and maximum 6 months to master Java. I would recommend you to watch all my videos to crack any software interviews that would require Java Programming language as a primary skill.

BiPredicate:
===========
1. It is a functional interface that was introduced in JDK1.8 version.
2. it is available in java.util.function package.
3. Please be informed that the BiPredicate will accept 2 arguments as the input and the return type is always boolean.
4. It has an abstract method which is test() method.
5. interface BiPredicate T,U
{
boolean test(T t,U u);
}
6. It is used extensively in functional programming and stream operations.
7. Please be informed that there are 3 default and 1 static method inside the predicate.
8. The default methods are and(), or() and the negate() method and their return type is BiPredicate itself and they are used to join two BiPredicate to full fill the most specific common requirements.
9. isEquals() method is a static method in the BiPredicate

BiFunction:-
=========

1. It is a functional interface that was introduced in JDK1.8 version.
2. it is available in java.util.function package.
3. It has an abstract method which is apply() method.
4. interface BiFunction T,U,R
{
R apply(T t,U u);
}
5. It is used extensively in functional programming and stream operations.
6. Please be informed that there are 2 default methods in the Function interface which are andThen() and compose() methods. They are used to write a complex function.
7. Please be informed that you want to pass 2 inputs as an argument to your Function, than you must choose the BiFunction.
