# 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.

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 [Centralizing File Delimited metadata](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/centralizing-file-delimited-metadata).
