Use them to review your candidates' answers.  Can you explain what JDK means? Junior Java developers should know that JDK is short for Java Development Kit. This technology package allows programmers to run Java programs on Java Virtual Machines and a Java Runtime Environment. Developers use this kit to implement specifications in Java, such as class libraries and a compiler. 2. Do you know how JVM, JDK and JRE are different? Candidates should be able to explain how these packages differ. First, they can explain that JDK (Java Development Kit) is a development kit that provides developers with an environment to run Java programs. Next, they should explain that developers use the JRE (Java Runtime Environment) to run programs and the JVM (Java Virtual Machine) to access a runtime environment and execute bytecode. 3. What do you know about type casting? Programmers use type casting to convert one data type to another.
