Answer 1

Do you mind showing me what is your text variable going to hold? What do you expect as an output and why do you need to make use of a toString()? It is generally used to describe object properties.

Answer 2

You can apply his example for every object.

Answer 3

Implement it. Use @Override annotation. If you have access to an IDE: They can auto-generate such methods.

Answer 4

I don't see the use of Document class here. You can simply override the toString() like this.

public String toSting(){
return "Sender: "+sender+"\nRecipient: "+recipient+"\nTitle: "+title;
}

And write something like this in main.

public static void main(String[] args) {

Email ob = new Email();
ob.setSender("Abc");
ob.setRecipient("Xyz");
ob.setTitle("Hello");
System.out.println(ob.toSting());

}

Answer 9

Sandra Meyer I have explained to Avinesh what exactly I am looking for...if u have any idea then let me know

Answer 10

Avinesh define a class named Document that contains a member variable of type String named text that stores any textual content for the Document. Create a method named toString that returns a text field and also include a method to set this value. Next, define a class Email which is derived from Document and includes member variables as sender, recipient,title of an email message. Implement accessor and mutator. The body of the email message should be stored in the inherited variable text. Redefine the toString method to concatenate all text fields.
