Using Java, you should not need createMemStorage, Java handles that kind of stuff for you, that is for c (not even c needs it according to the docs!) version of the library. The rest seem to mostly be in the org.opencv.imgproc namespace, which is explained in that link you provided;P.
The problem is that you're using ints instead of intobjs where you want to pass things around by reference (& in c). In your main function, you should try declaring i and j as intobjs and your parameter for fun, k should also be an intobj.

The CSV stands for Comma-Separated Values. It is a simple file format which is used to store tabular data in simple text form, such as a spreadsheet or database. The files in the CSV format can be imported to and exported from programs (Microsoft Office and Excel) which store data in tables. The CSV file used a delimiter to identify and separate different data token in a file. The CSV file format is used when we move tabular data between programs that natively operate on incompatible formats. There are following ways to read CSV file in Java. The default separator of a CSV file is a comma (,).

How to create CSV File

There are two ways to create a CSV file:

Using Microsoft Excel
Using Notepad

Using Microsoft Excel

Step 1: Open Microsoft Excel.

Step 2: Write the following data into the file:

Step 3: Now, save the file. Provide the file name CSVDemo and select CSV (Comma delimited) from the save as type menu. Now, click on the Save button.

Using Notepad

Unit 6 agendamrs. colvilles math class. Step 1: Open notepad.

Step 2: Write some data into file separated by comma (,). For example:

Vivek, Singh, 23, 9999999, Chandigarh

Step 3: Save the file with .csv extension.

We have created the following file.

Java Scanner class

Java Scanner class provide various methods by which we can read CSV file. The Scanner class provides a constructor that produces values scanned from the specified file. It breaks data into the token form. It uses a delimiter pattern which by default matches white space. The resulting tokens then converted into values of different types using the next() methods.

Example

Output:

Java String.split() method

Java String.split() identifies the delimiter and split the rows into tokens.

Syntax

Part 2 : How To Convert C To Java Programming | Tagalog

The method parses a delimiting regular expression. The method returns an array of string computed by splitting this string around matches of the given regular expression.

Consider the string:

'this:is:a:table'RegexResult : {'this', 'is', 'a', 'table'}

Example

In the following example, we use BufferedReader class which reads file line by line until the EOF (end of file) character is reached.
