How to override toString()

Vashudev

Hi!
I need to override toString() method to print the name of the object. I am assigning the "this" variable in a method to a string object(str = this.toString() and printing the name of the object using System.out.prinln(str) but doing that also prints some hex code and @ sing, I asked this question before somewhere else but the replies weren't very understnadable.
Please help
Thanks!

You can override that like any other overriden method:
[code]
class HelloWorld {

public String toString() {
return 'Hello World!';
}

}
[/code]

You're really looking for a way to access the name of the variable that refers to your object. This is not straightforward in Java.

I've found something that may be useful in looking for 'Introsector' on the sun website.

Good luck!

inside your class you could use something like

[code] public String toString() {
return this.getClass().getName();
}[/code]

which will return the name of the class.

toString is mostly used when you try to print a class's object using System.out.println and pass the object as a parameter to this function. I think if one makes a habit to always override toString method then only all classes in application will allow printing important information about object using SOP How to implement toString method in Java
