Why Do You Need a Java Test?
Description
Java is a platform-free programming language that retained its prominence for years because of its “write once, run anywhere” functionality, a vast ecosystem of built-in functions and libraries, and a large global community. For years, industry professionals have been using Java to build enterprise, mobile (especially Android), web, and desktop applications. Even global tech giants such as Google, Amazon, Microsoft, and Facebook are no exception to this. Companies working on modern-day technologies such as big data, cloud computing, IoT, and machines look for highly competent Java developers with comprehensive skill tests. To find the best talent, a comprehensive candidate evaluation is essential. In fast-paced hiring cultures, a part of this evaluation is to quickly validate a candidate's practical skills. To facilitate this skill-based hiring, a variety of coding and noncoding assessments are available that let you screen talented individuals and make informed hiring decisions.

Key Area in Java Screening Test
A Java screening test evaluates candidate performance in all important areas. From basic concepts to complex coding challenges, a Java test can include questions from various topics. Some key areas in a Java screening test are:
Basic Java Concepts
Object-Oriented Programming (OOP)
Data Structure
Data Algorithms
Exception Handling
Concurrency and Multithreading
Java I/O
Basic Java Concepts
The basic Java concepts are the foundation of all Java programs so any Java test, especially the beginner one, should include questions on the following:
- Data types, variables, operators
- Loops, conditionals, and control flow
- String and array manipulations
Every Java developer should have a thorough understanding of the basic Java concepts.

Object-Oriented Programming (OOP)
Another fundamental Java concept is Object-Oriented Programming (OOP) which every mid-level to senior developer should be proficient in.
To write a maintainable and well-structured code in Java, one needs to understand the following OOP principles:
Classes: These are the blueprints that describe properties (attributes) and behaviors (methods) of objects. It is a must-learn OOP concept enabling developers to build customizable and reusable objects.
Encapsulation: It is the bundling of related data and methods into a structured unit/class which helps developers build maintainable, secure, and flexible applications.
Abstraction: It simplifies complex systems by showing only the necessary features of an object. It promotes the reusability of code and enhances its maintainability.
Inheritance: Inheritance in OOP promotes code reuse which is referred to when one class inherits properties and behaviors (methods and attributes) from another class.
Polymorphism: It is related to using different classes with the same interface that enables the developer to come up with a flexible, maintainable, and reusable code.
Data Structure
It questions a candidate's understanding of linear and non-linear data structures. Questions from this area can be related to the following common data structure in Java, including:
Array
Linked List
Stack
Queue
Binary Tree
Binary Search Tree
Heap
Hashing
Graph
Data Algorithms
Common Java algorithms that can be a part of any Java test are:
Sorting
Searching
Graph
Dynamic programming
Recursion and backtracking
Bit manipulation
Divide and Conquer
Basic understanding of data structures and simple algorithms is a must for newbies. However, senior developer roles require working proficiency as well as ability to design and implement complex algorithms.
Exception Handling
The area assesses a candidate’s ability to handle exceptions (unwanted or unexpected events happening during the execution of a program). It helps to maintain program flow, prevent crashes, and write robust and reliable code.
These may include checked (checked at compile time), unchecked (checked at runtime), and error (serious issues) exceptions. This is a must-learn concept for junior, mid, and senior Java developers.
Concurrency and Multithreading
It covers questions related to concurrency which is related to the ability of your program to deal with multiple things independently in overlapping periods.
This concurrency is achieved through multithreading which is using multiple threads (small independent units of the program) within a single process. The understanding of both of these concepts is essential for developing responsive, scalable, and high-performance applications.
Mid-level and senior Java developers should have working proficiency in it. However, a basic understanding is sufficient for junior developers.
Java I/O
Questions in this area evaluate the candidate’s proficiency in I/O operations diving deep into understanding and execution of stream concepts alongside file handling. Basic knowledge of Java I/O is enough for beginners while mid-seniors and seniors should have command in it.
