Question: Which of the following statements is/are true about java.util.function.IntFunction?

Question: Code that uses generic collection classes can interoperate with code that uses raw collections classes because of? Select 1 option(s)byte code instrumentationjust in time compilationtype erasurereification5. Question: Is it possible to create arrays of length zero? Select 1 option(s):Yes, and it is same as a null Array.No, arrays of length zero do not exist in Java.Yes, you can create arrays of any type with length zero.Yes, but only for arrays of object references.Yes, but only for primitive datatypes6. Question: Which of the following are true regarding overloading of a method? Select 1 option(s):If there is another method with the same name but with a different number of arguments in a class then that method can be called as overloaded.An overloading method must have a different parameter list and same return type as that of the overloaded method.An overloaded method means a method with the same name and same number and type of arguments exists in the super class and sub class.If there is another method with the same name and same number and type of arguments but with a different return type in a class then that method can be called as overloaded.Time is Up!
