Can you explain what the term 'method overloading' means in object-oriented programming?

Method overloading is a feature in object-oriented programming that allows creating multiple methods with the same name but different parameters (type, number, or order). This enables using a single method name for different behaviors depending on the arguments passed.

For example, in Java, you can define several sum methods:

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

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

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

When called, the compiler selects the appropriate method based on the parameter signature. This simplifies the code and makes the class interface more convenient.
