conversion

[mn12]

Hi All,

Can I use the toString() method in order to convert an object to a String variable? How?

Thanks

I'm not entirely sure what you are getting at here, but this is how toString() works :

The class Object has a toString() method which is :

   // taken from the Sun src from SDK 1.4.1_02
    public String toString() {
	return getClass().getName() + "@" + Integer.toHexString(hashCode());
    }

.. so basically the class name and the class hash code.
If you called this code on an abject that did not override the toString() method :

Object o = new Object();
String s = o.toString();

Your String s would contain something like "java.lanf.Object@ae5hh7".


Other objects may override the toString() method to output different info, eg :

public class MyClass {

   public String toString() {
      return "Hello, this is the toString() method overridden");
   }
}

In this case, if you did this :

MyClass o = new MyClass();
String s = o.toString();

Your String s would contain "Hello, this is the toString() method overridden".

See ?!
