I was wondering if there is a good tool that can convert from C to Java. I remember seeing one such tool on github a long time back, but I can't find it anymore. It doesn't have to be a perfect translation; even if it gets me half-way there, it would help reduce the drudgery of manual translation. Based on your requirements, the Ispirer team will process all extension requests for your C/C to Java conversion project. We offer several types of Ispirer MnMTK licenses, among which you will find the one that is suitable for you.
Apr 13, 2014 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. Jul 27, 2008 c convert to java: converting c to java.

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 (,).
There are following ways to print an array in Java:
- Java Scanner class
- Java String.split() method
- Using OpenCSV API
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
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
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.
Output:
Using OpenCSV API
OpenCSV is a third party API which provide standard libraries to read various versions of CSV file. The library provides better control to handle the CSV file. The library can also read TDF (Tab-Delimited File) file format.
Features of OpenCSV
- Any number of values per line.
- Ignores commas in quoted elements.
- Handles entries that span multiple lines.
The CSVReader class is used to read a CSV file. The class provides CSVReader class constructor to parse a CSV file.
Syntax
Parameters
reader: The reader to a CSV source.
separator: It is a delimiter which is used for separating entries.
Steps to read CSV file in eclipse:
Step 1: Create a class file with the name ReadCSVExample3 and write the following code.
Step 2: Create a lib folder in the project.
Step 3: Download opecsv-3.8.jar from
Step 4: Copy the opencsv-3.8.jar and paste into the lib folder.
Step 5: Now, run the program.
Example
Output:
Reading CSV file with a different separator
In the following CSV file, we have used semicolon (;) to separate tokens.
