So maybe its best … Read more

ArrayList of int array in java
First of all, for initializing a container you cannot use a primitive type (i.e. int; you can use int[] but as you want just an array of integers, I see no use in that). Instead, you should use Integer, as follows: For adding elements, just use the add function: Last, but not least, for printing the ArrayList you may use the build-in functionality … Read more
