public void area(int a, int b, float c){
p = a;
q = b;
r = c;
}
}
Question 1:
which of the following methods overloads the above method and how??

Question 2:
for a mehtod to overload the argument list should be differenet. So, is the method overloaded if the aregument list changes its order


public void setVar(int a, float c, int b) {
area(a, b, c);
}


public void area(int a, float c, int b) {
this(a, b, c);
}

The signature is a combination of the name and parameter list. The order and type of the parameters are part of the signature.

The first method changes the name so it is not overloading area.

The second method does.

These are overloaded:

These are not overloaded (can you see why?):

This last one will not compile - two duplicate method signatures.

Also this(a, b, c) is being misused - it's only used in a constructor.
