4. Write a single if-test using Boolean operators and relaional operators to determine if a double variable x is between zero (exclusive) and one (inclusive). Print a message indicating that x is between zero and one inclusive. Use de Morgan's law to show the complement of the previous if-test. Simplify the complement statement so there is no "!" in your final if-test statement. 5. In the following questions, assume Boolean values have been assigned to A, B, and C as follows: boolean AA = true; boolean BB = false; boolean cc = true; Indicate what is printed by each statement: System.out.println( ((AA && BB) || (AA && CC) ) ); System.out.println( ((AA || !BB) && (!AA || CC) ); 6. Write a program to determine if an input integer is an even number or odd number. 7. How can the effect of the following program fragment best be described? if (x > y) z = x; if (x == y) z = 0; if (x
