Java Array Methods. Java's Arrays class in the java.util package offers a range of static methods facilitating operations on arrays. It provides functionality to fill, sort, search, and more. The methods enhance array manipulation, contributing to cleaner and more efficient code.
Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value. To declare an array, define the variable type with square brackets: String[] cars; We have now declared a variable that holds an array of strings.
This class contains various methods for manipulating arrays (such as sorting and searching). This class also contains a static factory that allows arrays to be viewed as lists. The methods in this class all throw a NullPointerException , if the specified array reference is null, except where noted.
