阅读更多关于 Convert ArrayList into 2D array containing varying lengths of arrays

So I have: ArrayList<ArrayList<String>> Which contains an x number of ArrayLists which contain another y number of Strings.. To demonstrate: Index 0: String 1 String 2 String 3 Index 1: String 4 Index 2: Index 3: String 5 String 6 Where index refers to the array index containing a string. How can I transform this into a 2D array which looks like: {{String1, String2, String3},{String4}, {}, {String5, String6}} Thank you so much. String[][] array = new String[arrayList.size()][]; for (int i = 0; i < arrayList.size(); i++) { ArrayList<String> row = arrayList.get(i); array[i] = row.toArray(new
