ArrayList without repetition
- by tuxou
Hi
i'm using arraylist in java and i need to add integers during 10 iteration (integer is got randomly from an array of integers named arrint) without any repetion:
for (int i =0; i<10; ++i)
array.add(integer);
and then add in the same array 20 other integers for the same array of integer(arrint) during 20 iteration without repetion
for (int i =0; i<10; ++i)
array.add(integer);
but repetition is permited between the 10 first integers and the 20 integers
thank you
