Java Coding Test (High)

Java is a multiplatform coding language that is used by programmers to design few implementations through its English-based commands. The first version of Java coding language was introduced in the year 1995 by James Gosling. Java Coding High test is based on the coding questions that help to assess the senior level knowledge of Java programming. This coding language is widely used in web development, android apps, big data, etc. The high-level Java programmer must have knowledge of some Java application containers, Big Data tools and Java automation apart from the basic coding.  

A few Java coding skills that you should learn as a high-level coder are:  

Technical Skills:

• Core Java 8
• Serialization in Java
• Java Frameworks
• Java Build Tools
• Web Technologies
• Java Testing Tools like Selenium
• Java Application Containers
• Big Data
• Java EE Components
• GitHub Version Control

Soft Skills:

iMocha's advance java coding test covers all the concepts of java programming and necessary for experienced level java programmers. This test contains high level coding questions assess the candidates without wasting time and money.

Tech recruiters/hiring managers can utilize features like coding simulators, LogicBox questions, Live coding interviews to assess Java coding skills of the developers. CodeReplay feature helps reviewer to replay screen capture of line-by-line code written by candidate. While, coding simulators comes with several candidate friendly features like default code stubs, intellisense, multiple test cases, so that candidates can focus more on algorithm to solve coding challenges. Hiring managers can use live coding interview to conduct coding assessments real time.
