Java (coding): data structures
This Java data structures test assesses a candidate's ability to effectively manipulate core data structures build-in the Java programming language. In 30 minutes, they will work with the core Java API to implement typical and real-life scenarios.
- Data structures
This test is relevant for
Any developer who is expected to have practical experience using Java. The difficulty level of these questions is geared to mid-level developers.
DescriptionJava is a general-purpose language used for distributed environments. It is one of the most popular programming languages for Android app development, embedded systems, desktop applications, and enterprise-grade systems.
Working with data structures is crucial to the success of a developer. Effective utilization of the core Java API and data structures enables developers to effectively organize, manage, and represent data. Data structures are often implemented as objects, so the ability to effectively work with objects and understanding object-oriented programming is an important skill to have.
This coding test presents a real-life scenario to your candidates. They have 30 minutes to implement a data structure that meets the given requirements. Candidates can run the code against a selected number of test cases to see if they are on track. After submission, the code is automatically scored based on another set of test cases that also covers exceptions or corner cases. You will be able to play back how the code came about in the coding editor.
We recommend combining coding tests with one of our cognitive ability tests.
