Checking an Object before you cast

[riches85]

I have a JTree that stores 1 of two different classes as objects in each DefaulyMutableTreeNode. Is it possible to check if casting the object to another class would raise an exception before I cast it. For example:

if( casting to string is valid )
String string = (String)myObject;

  Object o = new String("abc");
  boolean isString = o.getClass().getName().equals("java.lang.String");
  if (isString) {
     String s = (String)o;
  } else {
   // do something else
  }

  Object o = new String("abc");
  [b]if (o instanceof String) {[/b]
    String s = (String)o;
  } else {
  // do something else
 }
