I just want to  main call

(It is only one question)

Look at the code below. You have four classes (O, X, T, and M) and a variable of each of these.
O o;
X x;
T t;
M m;
The following assignments are all legal (assume that they all compile):
m = t;
m = x;
o = t;
The following assignments are all illegal (they cause compiler errors):
o = m;
o = x;
x = o;
What can you say about the relationships of these classes? Draw a class diagram.
