An array is an ordered collection of elements of the same type, identified by a pair of square brackets [].
To use an array, you need to:
1. Declare the array with a name and a type. Use a plural name for array, e.g., marks, rows, numbers. All elements of the array belong to the same type.
2. Allocate the array using new operator, or through initialization, e.g.
int[] marks; // Declare an int array named marks
// marks contains a special value called null.
int marks[]; // Same as above, but the above syntax recommended
marks = new int[5]; // Allocate 5 elements via the "new" operator
// Declare and allocate a 20-element array in one statement via "new" operator
int[] factors = new int[20];
// Declare, allocate a 6-element array thru initialization
int[] numbers = {11, 22, 33, 44, 55, 66}; // size of array deduced from the number of itemsCopyright © 2021 Codeinu
