Assume the following scenario. i call a method like this
String[] arr = {"1","2","3"};
method(arr);
and the method signature is
public void method(Object o)
{
// how will i get back the String[] arr object now..
}

The casting would look like this:
final String[] array = (String[]) o;

If you are writing
public void method(Object o) {
String[] arr = (String[]) o;
}
this means the only valid parameter type is String[] and you are better off making this clear with
public void method(String[] arr) {
}

Just cast it back.
String[] o2 = (String[]) o;
Comments
public void method(Object o) {
String[] arr = (String[]) o;
}
Here o is your passed String[] object. Just cast it to String[]. And if you are planning to pass an array every time then change your method signature to:
public void method(Object[] o)
