Every language — even English — has grammar rules.
Java has them too.
If you know these rules, your code will compile cleanly and run perfectly.
Break them → compiler errors 😬
So before building logic, you must understand how Java expects you to write code.
Syntax = The structure + grammar of Java code.
It defines how you must write your code so that the compiler understands it.
Example:
System.out.println("Hello, Java!");
If you forget the semicolon (;) 👇
System.out.println("Hello, Java!")
❌ You’ll get a syntax error — because you broke a grammar rule.
