Lambda expressions can contain a method body enclosed in braces with a return statement. This is called a block lambda. However, block lambdas can only be used when the functional interface's abstract method explicitly declares a return type. If the functional interface's abstract method does not explicitly declare a return type, then the lambda expression must be a single expression (i.e., without braces and without a return statement).
