An array is a data structure consisting of a collection of elements (values or variables), of the same memory size, each identified by at least one array index or key. An array is a linear data structure that stores similar elements (i.e. elements of similar data type) that are stored in contiguous memory locations. Static Array: Fixed size array (its size should be declared at the start and can not be changed later) Dynamic Array: No size limit is considered for this. (Pure dynamic arrays do not exist in Java. Instead, List is most encouraged.) To declare a static array of Integer, string, float, etc., use the below declaration and …Take a look at the documentation for Arrays.sort:.
