Java — Method Overloading

What is method overloading?

Multiple methods with same name but different parameters.

Example

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

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

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

Rules

• Different parameter types
• Different number of parameters
• Cannot overload by return type only

Mini Practice

1. Create overloaded methods
2. Use different types
3. Use different counts
4. Practice method overloading
