Why do I get an UnsupportedOperationException when trying to remove an element from a List?

Question

I have this code:

public static String SelectRandomFromTemplate(String template,int count) {
   String[] split = template.split(\"|\");
   List         


        

Answer 1

Arrays.asList() uses fixed size array internally.
You can't dynamically add or remove from thisArrays.asList()

Use this

Arraylist narraylist=new ArrayList(Arrays.asList());

In narraylist you can easily add or remove items.
