Adding elements of arraylist into array

Question

i have a huge amount of Strings generated after a system so the generation algorythm works fine. but i wanna save every single string in an arraylist first and after a specific amount i want to store the generated strings into an array and clear the arraylist so i can save another like 10 mil strings into the arraylist befor adding them to the array. and i tried the toArray method but ut overrides the existing entrys. if you have to know something else about this just ask.

Answer 1

Just make a method to merge two arrays! And then just keep adding the new one to the Array you want!
