a. What is the output of executing the following Java statements: {5 int x = 10, y = 20; boolean bl = true, b2 = false; boolean b3 = y < x; System.out.println("The value of b3 is " + b3); boolean b4 = b1 && b2; System.out.println("The value of b4 is " + b4); boolean b5 = b1 || b2; System.out.println ("The value of b5 is " + b5) ; %3D boolean b6 = bl * b2; System.out.println("The value of b6 is int z = (x == y) ? 5 : 0; System.out.println ("The value of z is " + z); + b6) ; b. Write Java statements to check whether the integer variable serial is positive, negative or zero. If it is positive print out the number is a positive number, and if it is negative print ou the number is a negative number, and if it is zero print out the number is zero. [5 marks %3D

boolean b5 = b1 || b2;
" + b5) ;
System.out.println("The value of b5 is
b1 ^ b2;
boolean b6 =
System.out.println("The value of b6 is " + b6);
int z = (x == y) ? 5 : 0;
System.out.println("The value of z is " + z);
b. Write Java statements to check whether the integer variable serial is positive, negative or
zero. If it is positive print out the number is a positive number, and if it is negative print out
the number is a negative number, and if it is zero print out the number is zero. [5 marks]
