of the getTitle method on the newly type-casted BlogPost instance.
I really dont understand what the question is asking me to do.
package com.example;
import java.util.Date;
public class BlogPost {
private String mAuthor;
private String mTitle;
private String mBody;
private String mCategory;
private Date mCreationDate;
public BlogPost(String author, String title, String body, String category, Date creationDate) {
mAuthor = author;
mTitle = title;
mBody = body;
mCategory = category;
mCreationDate = creationDate;
}
public String getAuthor() {
return mAuthor;
}
public String getTitle() {
return mTitle;
}
public String getBody() {
return mBody;
}
public String getCategory() {
return mCategory;
}
public Date getCreationDate() {
return mCreationDate;
}
}
import com.example.BlogPost;
public class TypeCastChecker extends{

BlogPost blogpost = (BlogPost) obj
Returning the title :
return blogpost.getTitle()
I also just started learning Java since 2 days ago so I'm not sure if it's right but you can at least try it ;)
