Reading Un-delimited text file in java via flatpack

Question

I want to read data from text file in java, but text file doesn't contain any delimiter like space or comma after some text. Some guy told me that its possible via flatpack.

So how can I read text and parse it as delimited and stored them.

Eg of text file data

"Prod Name" "City" "Price" "zipcode" "Date"

samsungA London 65001402110/07/2018  
samsungA California 35001202122/08/2018  
samsungA Delhi 44001202112/08/2018

I want to store: as:

Name in string  
City in string  
Price in int  
zipcode in int  
date as date

Any view on how to achieve this?

    Well you can use parser, and xml schema to define the length of the required variables that way one can extract the required varaibles. But yes, those variables will have predefined length.
    String data= "samsungA500";
    String schema = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n" + 
                    "<!-- DTD can be pulled from the Jar or over the web -->\r\n" + 
                    "<!DOCTYPE PZMAP SYSTEM  \"flatpack.dtd\" >\r\n" + 
                    "<!--<!DOCTYPE PZMAP SYSTEM \"http://flatpack.sourceforge.net/flatpack.dtd\"> -->\r\n" + 
                    "<PZMAP>\r\n" + 
                    "   <COLUMN name=\"std_name\" length=\"9\" />\r\n" + 
                    "   <COLUMN name=\"std_price\" length=\"3\" />\r\n" +  
                    "</PZMAP>";

InputStream mapping = new ByteArrayInputStream(schema.getBytes());
        InputStream dataStream = new ByteArrayInputStream(data.getBytes());    
Parser pzparser = DefaultParserFactory.getInstance().newFixedLengthParser(mapping, dataStream);
            DataSet ds = pzparser.parse();
while (ds.next()) {
                System.out.println(ds.getString("std_name"));
                System.out.println(ds.getInt("std_price"));
                System.out.println(ds.getString("std_name"));
            }
