- [Instructor] Generic methods in Java are methods that allow you to create a new type parameter just for that method. This is useful if you are writing a method but want to be flexible about the type of objects you can pass in. In this example, I have an array of characters called charArray. I also have an array of booleans called boolArray, and an array of integers called intArray. Then, I have created a method called arrayToList that iterates through all of the objects in an array and adds them to a list. I want to be able to pass any of these arrays into the method, even though they are of different types. So the first thing I have tried is making the arguments of the array to list method object types. In Java, object is a parent type of all other object types, so I can pass in arrays and lists of any types to this method. In the main method, I have used the array to list method to create a list of characters from charArray, a list of booleans from boolArray, and a list of…
