Exam 1z0-819 topic 1 question 160 discussion

D: Predicate function = s -> s.contains("N"); not correct syntax raw type Predicate class is considering parameter "s" as a type of Object so there is an exception MyClass.java:4: error: cannot find symbol Predicate function = s -> s.contains("N"); should be Predicate<String> function = s -> s.contains("N");

D:=> removeif accept a predicated only

Tested: D. Actually: Predicate<String> function = s -> s.contains("N");

D is Correct A List of String objects representing states is created and assigned to the states variable. A Predicate<String> functional interface is created using a lambda expression and assigned to the function variable. The lambda expression checks if a given String contains the character "N".The removeIf() method is called on the states list, passing in the function variable as an argument. This method removes all elements from the list that satisfy the given predicate. So, at the end of the program, all elements in the states list that contain the character "N" will be removed.
