Example 1: java arraylist to string
ArrayList<String> al = new ArrayList<String>();
al.add("Hello");
al.add("Wor");
al.add("ld");
StringBuffer sb = new StringBuffer();
for (String s : al) {

String str = sb.toString();
System.out.println(str);
Example 2: arraylist string to string array

List<String> stringList = new ArrayList<String>(Arrays.asList(strings));
