Java supports method name overloading so that multiple methods can share the same name.
For example
class DataRenderer
{
void draw(String s)
{
. . .
}
void draw(int i)
{
. . .
}
void draw(float f)
{
. . .
}
}
Overloaded methods are differentiated by the number and type of the arguments passed into the method.
In the code sample, draw(String s) and draw(int i) are distinct and unique methods because they require different argument types.
We cannot declare more than one method with the same name and the same number and type of arguments because the compiler cannot differentiate them. So, draw(String s) and draw(String t) are identical and result in a compiler error.
A class may override a method in its superclass. The overriding method must have the same name, return type, and parameter list as the method it overrides.
