Question

char[][] array1 = new char[15][10];


What is the value of array1.length?
0
2
10
15

Answer 1

Answer:The answer to this question is 15

Explanation:

array1.length contains the number of rows.Since a 2-D array is a 1-D array of 1-D arrays.So the value of array1.length will be 15 and the value of array1[0].length will be 10 that is the number of columns.So we conclude that the answer is 15 that is the number of the rows.
