Answer
Use a List to represent the 'many' side in Java.
In a one-to-many relationship, one entity is associated with multiple instances of another. In Java, this is often represented using a List. For instance, a 'Customer' class could have a List to represent multiple orders associated with a single customer. Careful handling of loading strategies is important to ensure performance, especially in JDBC without ORM tools.
