• Class.getName()
• Particular Sytntax in Generic Programming:
  • We can use <T extends A> to capture relationship between type in generic programming.
  • We can use <T extends A & X> to capture that T extends both A and X. Java uses the same extends keyword even if say, X is an interface.
• When using array initializer {1,2,3,4} in generic programming→ use instead like this → by specifying type: new Integer[]{1,2,3,4} → otherwise java make convert it to primitive type int which is not supported in generic types.
