Java’s basic syntax is the set of rules that defines the combinations of symbols that are considered to be correctly structured programs in the Java programming language. Understanding these rules is crucial for writing syntactically correct code that can be compiled and executed.

A Java program consists of a sequence of instructions that the computer can execute. These instructions must be written in a specific format that adheres to Java’s syntax rules. For instance, every Java program must have at least one class definition, and the main method serves as the entry point for execution. Syntax rules also dictate how to use loops, branches, and subroutines effectively ².

Identifiers, which are names for classes, methods, and variables, must follow specific conventions. They should begin with a letter and can include letters, digits, underscores, or dollar signs. Java is case-sensitive, meaning that thisVar and ThisVar are considered different identifiers. Additionally, naming conventions suggest that class names start with a capital letter, while method and variable names start with a lowercase letter ⁴.
