Finding length of all arrays multidimensional array, Java

java arrays multidimensional-array variable-length

Try using array[0].length, this will give the dimension you're looking for (since your array is not jagged).

java arrays multidimensional-array variable-length

boolean[][] array = new boolean[3][5];

Creates an array of three arrays (5 booleans each). In Java multidimensional arrays are just arrays of arrays:

array.length

gives you the length of the "outer" array (3 in this case).

array[0].length

gives you the length of the first "inner" array (5 in this case).

array[1].length

and

array[2].length

will also give you 5, since in this case, all three "inner" arrays, array[0], array[1], and array[2] are all the same length.

array[0].length would give you 5
