Using the sample below, we are going to illustrate how to extract the data that we want using the SDK.

Field Types
Standard Fields
These fields are generic and used in several products.
BaseField
Each prediction object contains a set of fields that inherit from the generic BaseField class. A typical BaseField object will have the following attributes:
confidence (Double): the confidence score of the field prediction.
boundingBox (Polygon): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.
polygon (Polygon): contains the relative vertices coordinates (polygon extends List<Point>) of a polygon containing the field in the image.
pageId (Integer): the ID of the page, always null when at document-level.
A Point simply refers to a List of Double.
Aside from the previous attributes, all basic fields have access to a custom toString method that can be used to print their value as a string.
StringField
The text field StringField extends BaseField, but also implements:
value (String): corresponds to the field value.
rawValue (String): corresponds to the raw value as it appears on the document.
DateField
The date field DateField extends BaseField, but also implements:
value (LocalDate): an accessible representation of the value as a Java object. Can be null.
