Executing query and insert operations using a Java client

In this recipe, we will look at executing the query and insert operations using a Java client for MongoDB. Unlike the Python programming language, Java code snippets cannot be executed from an interactive interpreter. Thus, we will have some unit test cases already implemented; their relevant code snippets will be shown and explained.

Getting ready

For this recipe, we will start a standalone instance. Refer to the Single node installation of MongoDB recipe in Chapter 1, Installing and Starting the MongoDB Server, to learn how to start the server.

The next step is to download the mongo-cookbook-javadriver Java project from the book's website. This recipe uses a JUnit test case to test various features of the Java client. In this whole process, we will make use of some of the most common API calls and, thus, learn to use them.

How to do it…

To execute the test case, one can either import the project in an IDE such as Eclipse and execute...
