Question

Java

Define a class called BlogEntry that could be used to store an entry for a Web log.

The class should have instance variables to store :

- the poster’s username,

- text of the entry,

- and the date of the entry using the Date class

Date class is:

class Date

{

private int day, year;

private String mon;

public Date()

{

mon=" ";

day=0;

year=0;

}

public String toString()

{

return (mon+"/"+day+"/"+year);

}

public set_date(String m, int d, int y)

{

mon=m;

day=d;

year=y;

}

}

Methods:

-Add a constructor that allows the user of the class to set all instance variables.

-Also add a method, DisplayEntry()/toString(), that outputs all of the instance variables,

- method called getSummary that returns the first 10 characters from the text (or the entire text if it is less than 10 characters).

.

my code so far:

import java.util.Scanner;

public class BlogEntry
{
   private String name;
   private String entry;

   public BlogEntry(String n, String e, String m, int d, int y)
   {
       System.out.println("Poster's name: "+n+"\nEntry Text: "+e);
       System.out.println("Date: "+m+" "+d+", "+y);
   }
   public String getName()
   {
       return name;
   }
   public void setName(String n)
   {
       this.name=n;
   }
   public String getEntry()
   {
       return entry;
   }
   public void setEntry(String e)
   {
       this.entry=e;
   }
   class date
   {
   private int d, y;
   private String m;
   public date(String m,int d, int y)
   {
       m= " ";
       d=0;
       y=0;
   }
   public void setdate(String m, int d, int y)
   {
       m=m;
       d=d;
       y=y;
   }
   }
private void String setSummary()
   {
   String summary=" ";
   int space=0;
   int script=0;
   while(space<=9 && script<entry.length())
   {
       String next=entry.substring(script,script+1);
       if(next.equals(" "))
       {
           if(space<=9)
               space++;
           else
               break;
       }
       summary+=next;
       script++;
   }
   return summary;
   }
   public getSummary()
   {
       return summary;
   }

public static void main(String [] args)
{
String name;
String entry;
String month;
int day;
int year;

Scanner input=new Scanner(System.in);

System.out.println("Please enter the Poster's name: ");
name=input.nextLine();

System.out.println("What is the text for the blog entry: ");
entry=input.nextLine();

System.out.println("What is the date of the entry?");
System.out.println("Please enter the month: ");
month=input.nextLine();
System.out.println("Please enter the day: ");
day=input.nextInt();
System.out.println("Please enter the year: ");
year=input.nextInt();

System.out.println("\nBlog Entry:");
BlogEntry entry1= new BlogEntry(name,entry,month,day,year);
BlogEntry entry2= new BlogEntry(name,entry,month,day,year);
entry2.setSummary(entry);
System.out.println("\nThe summary of this entry is "+entry2.getSummary);
  
  
  
  
}

}

.

.

.

the error is occuring for my getSummary and setSummary

BlogEntry.java:47: error: '(' expected private void String setSummary() ^

BlogEntry.java:67: error: invalid method declaration; return type required public getSummary() ^

//Try this Java code

class Date

{

    private int day, year;

    private String mon;

    public Date()

    {

        mon=" ";

        day=0;

        year=0;

    }
    //overload constructor

    public Date(int day, int year, String mon) {
        this.day = day;
        this.year = year;
        this.mon = mon;
    }

    @Override
    public String toString()

    {

        return (mon+"/"+day+"/"+year);

    }

    public void set_date(String m, int d, int y)

    {

        mon=m;

        day=d;

        year=y;

    }
