how to declare an array in java
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 items
