Code Examples

Variables & Types

int age = 25;
float pi = 3.14f;
string name = "Alice";
bool active = true;
double result = 42.5;

Functions

public int add(int a, int b) {
    return a + b;
}

int sum = add(10, 20);
print(sum); // Output: 30

Classes

class Calculator {
    int value = 0;
    
    public void add(int x) {
        value = value + x;
    }
}

Loops

for (int i = 0; i < 5; i = i + 1) {
    print(i);
}
// Output: 0 1 2 3 4

Conditionals

int age = 18;
if (age >= 18) {
    print("Adult");
} else {
    print("Minor");
}

Arrays

int[] numbers = new int[5];
numbers[0] = 10;
numbers[1] = 20;
print(numbers[0]); // Output: 10
