Mathematical functions

Hi,

Are you refer to the pointer to function used in C?

This may not be the correct approach but it may offer something close to what you are looking for:

public class Test

{

public static void main(String[] arg)

{

Common c = null;

if(arg[0].equals("0"))

{

c = new Add();

}

else

c= new Sub();

Test tt= new Test();

tt.test(c,2,1);

}

public void test(Common c, int a, int b)

{

System.out.println(c.function(a,b));

}

}

interface Common

{

public int function(int a, int b);

}

class Add implements Common

{//this is the add function

public int function(int a, int b)

{

return a+b;

}

}

class Sub implements Common

{

public int function(int a, int b)

{

return a-b;

}

}
