}

The Java code to be created is similar to how to add an array to a mongodb document using Java?

Is there any code to programmatically create objectid ("") in Java?

Solution

To programmatically create an objectid, use the following syntax

ObjectId id = new ObjectId();

or

ObjectId id = ObjectId.get();

If you want to mention the parent ID itself,

then

ObjectId id = new ObjectId("5399aba6e4b0ae375bfdca88");
