go - Get dimensions of 2d slice -


lets have 4 5 2d array

array := [][]byte{     {1, 0, 1, 0, 0},     {1, 0, 1, 1, 1},     {1, 1, 1, 1, 1},     {1, 0, 0, 1, 0}, }

how columns , widths of array? want nested loop on array array passed in function may vary in dimensions.

just len of array , len of element of array.

len(array) // 4 len(array[0]) // 5

as note, using 2d slice, not array. read more go slices here.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
