Analyze the following program fragment: int x; double d=1.5; switch (d){ case 1.0:x=1; case 1.5:x=2; case 2.0:x=3; \} a. The program has a compile error because the required break statement is missing in the switch statement. b. The program has a compile error because the required default case is missing in the switch statement. c. The switch control variable cannot be double. d. No errors. 25. What is y after the following statement is executed? x=0y=(x>b==b>a; System.out.printin((even ? "true" : "false")); a. true b. false c. nothing d. true false 28. What is y displayed in the following code? public class Test 1 f public static void main(String[] args) \{ int x=3; int y=x+= Math.pow (2,x); System.out.printin(" y is " + y); \} \} a. y is 0 b. y is 1 c. y is 11 d.
