Classify this statement as valid or invalid. final int x = 5; x = 6; 9. For what two word phrase is bit an abbreviation? 10. The function of the assignment operator (=) is a to process. 11. The term _ indicates that an operator performs a process of some sort on two values or objects. 12. Complete the statement. A Java constant is usually all letters. 13. Indicate the correct value in bits for memory storage for the data type listed. char ==> bits 14. Fill in the blank with the appropriate data type (int, double, String, char, boolean). d = -14.5; 15. What Java limit does this value represent? VALUE 16. Classify this identifier as valid or invalid for use in Java. 8ball
