Javier Gonzalez-Sanchez | CSE110 | Summer 2017 | 2 One-dimensional Array • A one-dimensional array stores a list of elements 0 0 0 0 0 0 0 1 2 3 4 5 int []array = new int [6] array
Javier Gonzalez-Sanchez | CSE110 | Summer 2017 | 3 One-dimensional Array • A two-dimensional array can be thought of as a table of elements, with rows and columns 0 1 2 3 4 5 int [][]array = new int [6][3] array 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 2
Javier Gonzalez-Sanchez | CSE110 | Summer 2017 | 4 Two-dimensional Array • A two-dimensional array is an array of arrays • A two-dimensional array is declared by specifying the size of each dimension separately int[][] scores = new int[12][50]; • A array element is referenced using two index values value = scores[3][6]
