Java interview is one of the tough interviews for developers coming from other technologies. So I have given very basic interview questions they asked. Really awesome to know these questions. 1. What is JVM? Why is Java called the ‘Platform Independent Programming Language’? JVM, or the Java Virtual Machine, is an interpreter that accepts ‘Bytecode’ and executes it. Java has been termed as a ‘Platform Independent Language’ as it primarily works on the notion of ‘compile once, run everywhere’. Here’s a sequential step establishing the Platform independence feature in Java: The Java Compiler outputs Non-Executable Codes called ‘Bytecode’. Bytecode is a highly optimized set of a computer instruction which could be executed by the Java Virtual Machine (JVM). The translation into Bytecode makes a program easier to be executed across a wide range of platforms since all we need is a JVM designed for that particular platform. JVMs for various platforms might vary in configuration, those they w...
