1. Java Variables, Types and Syntax

Variables and Types in Java

Java is a statically typed language. Every variable must have a declared type:

String baseUrl = "https://targetqa.com";
int timeoutSeconds = 30;
boolean isHeadless = true;
double responseTime = 1.45;
if (timeoutSeconds > 10) {
    System.out.println("Using extended timeout: " + timeoutSeconds + "s");
}
