What is the difference between
1)
public class USingP1: Strategy
Private P1 var1; ====>I declare a variable of the type above
2)
public class USingP1: Strategy
Add(P1(var1,var2)); ====>I use a variable of the type above
IN both statements recall an earlier indicator ... but which is the difference?
