Two-dimensional array lengths????

[Sam Bluesman]

How do I find out the length of a row in a 2-dimensional array. For exanmple if i have [x][y], how do i find the legnth of x? the .length method seems to give me the length of y.

Cheers

A two-dimensional array in Java is just an array of arrays. Try this:

String[][] data = new String[3][5];
int len1 = data.length;
int len2 = data[0].length;
System.out.printf("size is %d x %d%n", len1, len2);

Keep in mind that a 2-d array does not need to be "rectangular," and could contain arrays of different lengths.

For example, if "myArray" represents a 2-d array, then the array at myArray[0] is not necessarily the same length as the array at myArray[1]...

int[][] myArray = { {1}, {2, 3, 4}, {5, 6} };

Which also means that :
int[][] myArray = new int[3][];
myArray[0] = new int[1];
myArray[1] = new int[3];
myArray[2] = new int[2];
And you should not forget initialze the arrays

Do you mean like this:

int[][] myArray = { {1}, {2, 3, 4}, {5, 6} };
