In what way is static declaration different from dynamic declaration?

What do you mean by non-primitive data type? Give examples.

Predict the return data type of the following:

int p; double q;
r = p+q;
System.out.println(r);

What are the resultant data types if the following implicit conversions are performed? Show the result with flow lines.

int i; float f; double d; char c; byte b;

(a) i + c/b;

(b) f/d + c*f;

(c) i + f - b*c;

(d) (f/i)*c + b;

(e) i + f- c + b/d;

(f) i/c + f/b;
