Question

Just wondering, what would the best way for pulling information from headings in a String be.

I have a class and getter methods for the headings (Summary, Heading 1, Heading 2).

For example,

If I have a String equal to,

This: is the first line of a String: xx-string: This is a long String

Summary:
This is the summary of the String

Heading 1:
This is the first heading

Heading 2:
This is another heading

What would be a desirable way to set the value of the Strings,

Summary, Heading 1, Heading 2

to

Summary = This is the summary of the String
Heading 1 = This is the first heading
Heading 2 = This is another heading

Thanks !!

Edit

Here is what I was going for,

 public void setHeadings(Data fileData) {
        String description = fileData.getDescription();
        //String [] headings = description.split(":");

        int indexOf;
        indexOf = description.indexOf("Summary");
        if(indexOf != -1)
        {
            String subString = description.substring(indexOf);
            int indexOfNextHeading = subString.indexOf(":");
            if(indexOfNextHeading != -1)
            {
                System.out.println(indexOf + ":" + indexOfNextHeading);
                setSummary(description.substring(indexOf,indexOfNextHeading-1));
                System.out.println(description.substring(indexOf,indexOfNextHeading));
            }
        }
    } 

That however, spits out an Array Out of bounds exception.

Use a Scanner object.

import java.util.Scanner;

Then use it to read the String one line at a time.

Scanner sc = new Scanner(string);
sc.useDelimiter("\n");  // read one line at a time

Now sc.hasNext() tells you if there are lines left to read, and sc.next() returns the next line. Use this to iterate through the String one line at a time. You can test each line to see if it is equal to “Summary:” or “Heading 1:”, etc. Then you can use a StringBuffer to add each line from each String you want to create.

I can write this for you if you want, but it’s fairly simple.
