Please complete the following using the showInputDialog and showMessageDialog methods in the JOptionPane class in the javax.swing library:

Use the StringTokenizer class in the java.util library to isolate tokens in a string wherever there is a blank using the nextToken method, and the parseDouble method in the Double wrapper class to get three sides of a triangle and calculate the area of the triangle. Heres an example:

StringTokenizer st1 = new StringTokenizer(input1, " ");

double a = Double.parseDouble(st1.nextToken());

Use Heron's Formula:

Area of triangle = sqrt(p*(p-a)*(p-b)*(p-c)) where p = (a+b+c)/2

If the sum of any two sides is equal to or less than the third side, please put the message Invalid triangle.

Use the reverse and equalsIgnoreCase methods in the StringBuilder class to get a string, and then determine of it is a palindrome. A palindrome is a string that, if read frontwards and backwards, is the same.

1. Using the indexOf method in the String class, determine if a search string is contained inside a string to search. If so, please report the position of the search string. If the search string is not found, please indicate that the search string was not found.

Using the parseInt method with a radix of 16 argument in the Integer wrapper class, request a hex value and convert it to a decimal value

Using the split method from the String class, build a String array of tokens where each token is an address line. Split the string into tokens using a % sign. Output the address into correctly formatted address lines.
