Lambda Expressions (The Java™ Tutorials > Learning the Java Language > Classes and Objects)
However, when the Java runtime invokes the method printPersonsWithPredicate, it's expecting a data type of Predicate<Person>, so the lambda expression is of this type. The data type that these methods expect is called the target type. To determine the type of a lambda expression, the Java compiler ...

Java Lambda Expressions
A lambda expression can be stored in a variable. The variable's type must be an interface with exactly one method (a functional interface). The lambda must match that method's parameters and return type. Java includes many built-in functional interfaces, such as Consumer (from the java.util package) used with lists.
Any tips for understanding and practicing Java lambda expressions?

Java Lambda Expressions (With Examples)
The block body allows the lambda body to include multiple statements. These statements are enclosed inside the braces and you have to add a semi-colon after the braces. Note: For the block body, you can have a return statement if the body returns a value. However, the expression body does not require a return statement. Let's write a Java program that returns the value of Pi using the lambda expression.
