How to create a jar file using eclipse in 3 easy steps

A jar file is a Java ARchive file that contains many java .class files as well as other resource files in a compressed format.
It is similar to a tar or zip format.

Here are three simple steps with illustrations to create your jar file in Eclipse IDE.

Step 1 : Create your java class(es)

I have written a java class HelloWorld.java in Eclipse in a package called HelloWorld as shown below.

Step 2 : Choose the export file format

Now I want to put entire project in a jar file.
Right-click on the package and select export.

Now select under Java icon JAR as shown.

Step 3 : Specify the jar file name and location

I give the jar file name as C:\amol\HelloWorld.jar as shown

I check 'Export generated class files and Resources' and 'compress the contents of jar file' checkboxes.
Thats it.
Now just click finish and your jar file will be created at the given location.

How to convert a CSV file to XLSX

I wrote this utility for a friend of mine who wanted to convert large (~50MB) CSV files to XLSX. The CSV files had comma "," as a delimiter. I have used apache poi utility in this program. https://www.apache.org/dyn/closer.lua/poi/release/RELEASE-NOTES.txt This code uses SXSSFWorkbook class. The SXSSFWorkbook class uses "BigGridDemo" strategy, where only portions being processed are kept in memory. There are temporary files created which store the rest of the temporary data. setCompressTempFiles() method allows these temp files to be compressed. The size of these files can get quite large. The data to be converted was UTF-8 encoded data. So, we are using OutputStreamWriter, where we specify the encoding of the data. If you do not need the encoding, just remove that parameter from the constructor call of OutputStreamWriter. The system where this ran, supported Java 7, so have not used features in java 8, such as try with exceptions. import java.io.*; im...
