Question

I want to split a string and get a word finally. My data in database is as follows.

Mohandas Karamchand Gandhi (1869-1948), also known as Mahatma Gandhi, was born in Porbandar in the present day state of Gujarat in India on October 2, 1869.
He was raised in a very conservative family that had affiliations with the ruling family of Kathiawad. He was educated in law at University College, London.

From the above paragraph I want get the image name “gandhi”. I am getting the index of “src=”. But now how can I get the image name i.e “gandhi” finally.

My Code:

int index1;
public static String htmldata = "src=";
if(paragraph.contains("src="))
{
   index1 = paragraph.indexOf(htmldata);
   System.out.println("index1 val"+index1);
}
else
   System.out.println("not found");

Try this code. Check if it working for you..

public String getString(String input)
    {
        Pattern pt = Pattern.compile("src=.*/(.*)\\..*");
        Matcher mt = pt.matcher(input);
        if(mt.find())
        {
            return mt.group(1);
        }
        return null;
    }

Update:
Change for multiple item –

public ArrayList<String> getString(String input)
    {
        ArrayList<String> ret = new ArrayList<String>();
        Pattern pt = Pattern.compile("src=.*/(.*)\\..*");
        Matcher mt = pt.matcher(input);
        while(mt.find())
        {
            ret.add(mt.group(1));
        }
        return ret;
    }

Now you’ll get an arraylist with all the name. If there is no name then you’ll get an empty arraylist (size 0). Always make a check for size.
