11. What are order of precedence and associativity, and how are they used?

Ans:
Order of precedence determines the order in which operators are evaluated in expressions. Associatity determines whether an expression is evaluated left-to-right or right-to-left

12. What is the difference between the Boolean & operator and the && operator?

Ans:
If an expression involving the Boolean & operator is evaluated, both operands are evaluated. Then the & operator is applied to the operand. When an expression involving the && operator is evaluated, the first operand is evaluated. If the first operand returns a value of true then the second operand is evaluated. The && operator is then applied to the first and second operands. If the first operand evaluates to false, the evaluation of the second operand is skipped.

13. Which Java operator is right associative?

14. Can a double value be cast to a byte?

15. What is the % operator?
