- Another cool feature of Java is that
methods in Java can easily be overloaded such that the
same method name can be used for several different
implementations of the same action. Remember our
previous example of printNumber(), printLetter(), printImage()?
- The only requirement for overloading
is that each version of the method takes a different set of
parameters as arguments (sometimes, we say that it has a
"different signature") such as in the following example:
int add(int a, int b)
{
return (a+b);
}
double add(double a, double b)
{
return (a+b);
}
float add(float a, float b)
{
return (a+b);
}
- Finally, it is worth noting that since
methods belong to specific classes, it is fine for you to have
the same method name with the same arguments in different classes.
Thus, the Button class might have a setLabel(String s) method and a
Label might have a setLabel(String s) method and neither will conflict
since each method is specific to a specific class.
