I need to write a java program using Netbeans with it's scene builder. The goal is to create a letter frequency counter using a histogram layout and piechart layout as shown in the pictures below. I also need to follow the component layout as shown below. Basically what would the ending .java code and FXMLDocumentcontroller.java code look like after replicating the following layout?
