What is the Java notation for height in a 2D array?

[UrbanXrisis]

I know that in an array called math[][], the "math.length" will give me the length, or "width" of the array. What is the notation for the "height"?

Ex, if math[][] was a 12x15 array, then math.length=12. how would I get the # 15?

I'm not sure there is a method for that. Since you know that you have 12 one-dimensional arrays of length 15, I think you could store one of those arrays in another 1D array and then apply myArray.length to get the 15.

The notation for the "height" in a 2D array in Java is simply the length of the second dimension. In your example, the "height" would be accessed by using math[0].length, which would return the value 15. This is because the first dimension represents the rows and the second dimension represents the columns in a 2D array. Therefore, to get the "height" of the array, you would need to access the length of the second dimension.
