The following code segment is intended to round yal to the nearest integer and print the result double val--0.7 int roundedVal (int) (val +0.51 System.out.println(roundedValu 25 Mark for Review Which of the following best describes the behavior of the code segment? The code segment does not work as intended because the expression (val +0.5) should be cast to a double instead of an int The code segment does not work as intended because val should be cast to an int before 0.5 is added to it. Highlights & Notes Reference Undo Undo The code segment does not work as intended because the expression -Unda positive ר .

In the following code segment, mon and tue are properly declared String variables. String strl-mon.substring(9. mon.indexOf(" "). String str2-tue.substring(tue.indexOf(" ") + 1). System.out.println(strl+and+str2): க 21 Mark for Review For which of the following values of mon and tue will the code segment print "cloudy and foggy"? mon tue "cloudy today" "foggy tomorrow" mon tue "cloudy today" "tomorrow foggy" mon tue "today cloudy" "foggy tomorrow" mon tue "today cloudy" "tomorrow foggy"

G Consider the following code segment, which is intended to assign to num a random integer value between min and max, inclusive, each with an equal chance of being assigned to num. Assume that min and max are integer variables and that the value of max is greater than the value of min. 24 Mark for Review Which of the following can replace /* missing code */ so that the code segment works as intended? double rn = Math.random();_ int num = /* missing code */ ;_ D (int) (rn * max) + min ABC (A) (int) (rn * (max- min)) + min (B (int) (rn * (max min)) + 1 (int) (rn * (max min + 1)) + min

(团) (四) The Dog class has a constructor that takes two parameters. The first parameter is a String representing a dog's name and the second parameter is an int representing the dog's age, in months. 9 Mark for Review ARC The following code segment appears in a class other than Dog. Which of the following best describes the contents of dog1 and dog2 as a result of executing this code segment? Dog dogl new Dog ("Rex", 4); Dog dog2 dogl dog1; new Dog("Fido", 60); dog1 and dog2 are Dog variables that each contain the same Dog object, which represents a dog named "Fido' that is 60 months old. dogl is a Dog variable that contains a Dog object representing a dog named "Fido" that is 60 months old, and dog2 is a Dog variable that contains a Dog object representing a dog named "Rex" that is 4 months old. dogl and dog2 are Dog reference variables that each contain a reference to the same memory address that contains the Dog object representing a dog named "Fido' that is 60 months old. dogl is a…

The following code segment is intended to assign to newword the result created by removing the first occurrence of "a" from word. Assume that the String variable word has been properly declared and initialized. This code segment works for some, but not all, values of word. int aLoc word.indexOf("a"); String newword word.substring(0, aLoc) + word.substring(aLoc + 1); 18 Mark for Review Which of the following conditions best describes the condition in which this code segment will not work a intended and will result in a runtime error? is the first character in word. is the last character in word. word does not contain the character "a". word contains only a sequence of multiple "a" characters.
