# Converting java types

This Java scenario describes a four-component Job where the tConvertType component is used to convert Java types in three columns, and a tMap is used to adapt the schema and have as an output the first of the three columns and the sum of the two others after conversion.

For more technologies supported by Talend, see [Talend components](https://help.qlik.com/talend/r/en-US/7.3/components/processing).

Information noteNote:

In this scenario, the input schemas for the input delimited file are stored in the repository, you can simply drag and drop the relevant file node from Repository - Metadata - File delimited onto the design workspace to automatically retrieve the tFileInputDelimited component's setting. For more information, see *Talend Studio User Guide*.
