Programming Language Comparisons ⚖️

Mentor's Note: Learning your first language is hard. Learning your second is easy! This page helps you see that while Syntax changes, the Logic is universal. 💡

🏗️ Core Logic Side-by-Side

1. Printing to Screen

How to say "Hello" to the world.

Language	Code Syntax
Python	print("Hello")
Java	System.out.println("Hello");
C	printf("Hello\n");
JavaScript	console.log("Hello");
PL/SQL	DBMS_OUTPUT.PUT_LINE('Hello');

---

2. Variables (Storing Data)

Labeled boxes for your information.

Language	Code Syntax	Type
Python	x = 5	Dynamic 🪄
Java	int x = 5;	Static 🧱
JavaScript	let x = 5;	Dynamic 🪄
PL/SQL	v_x NUMBER := 5;	Static 🧱

🚦 Logic & Control Flow

3. Conditional (If-Else)

Making decisions based on a condition.

PythonJava / JS / CPL/SQL

if age >= 18:
    print("Vote ✅")
else:
    print("Wait ⏳")

if (age >= 18) {
    System.out.println("Vote ✅");
} else {
    System.out.println("Wait ⏳");
}

IF v_age >= 18 THEN
    DBMS_OUTPUT.PUT_LINE('Vote ✅');
ELSE
    DBMS_OUTPUT.PUT_LINE('Wait ⏳');
END IF;
