How to add a string into an array list in java

Question

I try to add a string "hello" into an array list, and convert the array list back into a string array, but I get weird output like this: [Ljava.lang.String;@1f26ecd2. What's the problem with that?

String s="hello";
   ArrayList<String> base = new ArrayList<String>();
   int a=0;
   if(a==0)
   {
       base.add(s);
   }
        String[] get=base.toArray(new String[base.size()]);
        System.out.print(get);

You need to use a loop to cycle get array to print its element. If you print directly the array of string, you get the objec codename

If you want to print array values, use Arrays.toString()

System.out.print(Arrays.toString(get));

It's not an error.. change the last line of that code to

System.out.print(get[0]);
