Converting an Array to an ArrayList in Java
One of the most common operations in programming is converting data structures from one type to another. In Java, this task is made easier by the Arrays.asList() method, which can be used to convert an array to an ArrayList.
Problem
Suppose you have an array of elements stored in the variable array as follows:
Element[] array = {new Element(1), new Element(2), new Element(3)};
How can you create an ArrayList of elements using the values from this array?
Solution
To convert the array array to an ArrayList, you can use the Arrays.asList() method. This method takes an array as an argument and returns a new ArrayList containing the elements of that array. The resulting ArrayList will be immutable, meaning that its elements cannot be modified.
Here's how you can use the Arrays.asList() method to create an ArrayList from the array array:
ArrayList<element> arrayList = new ArrayList(Arrays.asList(array));</element>
This will create a new ArrayList called arrayList that contains the elements from the array array.
