Exception handling: In Java, the exception is an object used to signal the unexpected error occurred during a program execution. Exception is the error, which arises at run time and such errors can be handled in Java by exception handler.

Question

public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string. This problem is an exercise in Java string manipulation. For some mysterious reason, the Java String type does not come with a reverse method. The canonical way to reverse a Java string str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result back to an immutable string, that is, str = new StringBuilder(str).reverse().tostring(); A bit convoluted, but does what is needed without fuss or muss. Maybe one day the Java strings will come with the reverse method built in, just like the string data types of all sensible…

Please read my question and help me answer! Thanks! public class CustomString { String myString; boolean isSet; public CustomString() { // TODO Implement constructor this.myString = null; this.isSet = false; } /** * Returns a new string version of the current string where the capitalization is reversed (i.e., lowercase to uppercase, * and uppercase to lowercase) for the alphabetical characters specified in the given arg. * * All non-alphabetical characters are unaffected. * If the current string is null, empty, or has not been set to a value, this method should return an empty string. * * Example(s): * - For a current string "abc, XYZ; 123.", calling reverse("bcdxyz@3210.") would return "aBC, xyz; 123." * - For a current string "abc, XYZ; 123.", calling reverse("6,.") would return "abc, XYZ; 123." * - For a current string "abc, XYZ; 123.", calling reverse("") would return "abc, XYZ; 123." * - For a…
