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;
