ABSTRACT
This chapter explains how to install and run Java on a personal computer. The Java file is converted by Java compiler (which does not interface with the operating system) at compile-time, which turns the Java code into bytecode. The bytecode of the file in the classloader is verified and leads to the interpreter. The code is interpreted, proceeded to runtime, and implemented in hardware. The Java compiler runs the code from beginning to end. The statements in the code are executed in the order that they occur in the code. Java, on the other hand, statements that can be used to regulate the flow of Java code are available. The if statement is the simplest way to make a choice. It is used to determine if a statement or a block of statements will be executed or not, i.e., if a condition is true, a block of statements will be performed; otherwise, it will not.
