Apache POI Pivot Tables- How to use the "In-Between" Value Filter in Java

I am trying to design a pivot table using Apache POI, and what I want to do is to initially print the sum value which is greater than a certain number, as well as less than a certain number. However, when I try and do this, the filters cancel each other out, which means that sum values are printed that should not be there. For example, if I want the sum to be between 2 and 5, the sum value of 1, as well as numbers greater than 5, both get printed out. Here is the code that explains my problem:

This is the pivot table that gets printed as a result of running this code:

If you have any idea on how to help me with this, please let me know!

Well, how to get what needs to be set for the *.xlsx file? The *.xlsx is simply a ZIP archive. So one can unzip the *.xlsx and have a look what is inside it.

So do what you need using Excel's GUI, save the *.xlsx, then unzip it and have a look at /xl/pivotTables/pivotTable1.xml. There you will find the following filter setting:

<filters count="1">
<filter fld="1" type="valueBetween" evalOrder="-1" id="1" iMeasureFld="0">
<autoFilter ref="A1">
<filterColumn colId="0">
<customFilters and="1">
<customFilter operator="greaterThanOrEqual" val="2"/>
<customFilter operator="lessThanOrEqual" val="5"/>
</customFilters>
</filterColumn>
</autoFilter>
</filter>
</filters>

So customFilters needs the setting that the following filters are AND linked. This is what your code does not set yet.
