Public Static Int Compareto Range Ri Range R2 Question 8 Compares Two Range Instances Widt Q43815164

public static int compareTo(Range ri, Range r2) [Question 8] Compares two Range instances by their widths. Parameters: r1 – a Range r2 – a second Range Returns: the value o if both Range instances are equal; -1 if r1 is narrower than r2; and 1 if r1 is wider than r2 public static boolean hasValidLengthAndSeparator (String s) [Question 9] Partially validates a string that is supposed to represent a time on a 24-hour clock. Returns true if: • the string has length equal to 5, AND • the third character is a colon : and false otherwise. Parameters: S – a string to validate Returns: true if the string length is 5 and the third character is a colon, and false otherwise public static void sort2(List<Integer> t) [Question 10a] Sorts a list of two integers so that the elements are in ascending order. The size of the list remains unchanged. Parameters: t – a list Throws: IllegalArgumentException – if the size of list is not equal to 2 public static void toRadians(List<Double> t) [Question 10b] Replaces the elements of a list of angles in degrees with the equivalent angles in radians. The size of the list remains unchanged. Parameters: t – a list of angles in degrees Show transcribed image text public static int compareTo(Range ri, Range r2) [Question 8] Compares two Range instances by their widths.
