Create Random Alphanumeric Cha

Question

Hi,

Is there a way to generate alphanumeric characters of a certain size and add them to the string array and get each created by index number or add them to an ArrayList?

I tried the below code but it not working.

Is there a solution?

Answer 1

So are you wanting to build a random alphanumeric string of size and find the position specific character? Theres a method called indexOf("letter"); which will give you the position if that helps?.

heres an example

System.out.print("hello".indexOf("o")+1);

D_Stark thanks for your answer. What I want is to create random alphanumeric string array like {hdy276HFvD, ghdYE63bdj, IDBvdj393g} but not a single string. The alphanumeric created can also be added to ArrayList.
