Method overloading is compile time polymorphism and method
overriding is Runtime polymorphism.
Method overloading is having same name and different
parameters and different return type also. But same type and
same no:of parameters but different return type is not allowed.
Error while compile: type methodname(type name) is already
defined in classname.
Method overriding same name with same parameters and having
same return type in different class while inheritance is
applied.


Try this following program: this will throw a error while
compiling.....
class OverloadDemo {
int test(int x) {
return x*x;
}

long test(int a) {
long l = a*a*a;
return l;
}

double test(double a) {
return a*a;
}

}
