public class kaashiv_infotech
{
public static void main(String args[])
{
String[] strvalues = new String[]{"mani", "Tiger", "kishore", "Jana"};
List<String> arrlist = Arrays.asList(strvalues);
Collections.reverse(arrlist);
strvalues = (String[]) arrlist.toArray();
System.out.println("reversed String array ");
for(int i=0; i < strvalues.length; i++)
{
System.out.println(strvalues[i]);
}
}
}Output:
reversed String array
Jana
kishore
Tiger
