The hashCode() method in Java returns the hash code value of a List instance. This hash code value is typically used in hash tables to quickly look up the object.
List colors = new ArrayList<>(); colors.add("red"); colors.add("blue"); colors.add("green");
int hash = colors.hashCode(); System.out.println("List hash code: " + hash);
In this example, we create a List of strings and add some colors to it. We then call the hashCode() method on the List instance and print out the hash code value.
This method is part of the java.util package, which is a standard library package in Java.
