Implement the following methods in a class named StringPlay:

// Write a method that returns true if s has leading or trailing whitespace, false otherwise

public static boolean needsTrim(String s)

// Write a method that swaps the first three and last four characters of s

public static String swap3For4(String s)

// Write a method that has one String parameter, and returns true if the first half and last half of the parameter are the same ignoring case, and false otherwise.

public static boolean areHalvesEqual(String s)

Create a class named StringPlayTester which only contains main(). In main, the user should be prompted to enter a string (I'll call it str). main() will then call each method in StringPlay passing str as the formal parameter as summarized below:

boolean result1 = StringPlay.needsTrim(str);

String result2 = StringPlay.swap3For4(str);

boolean result3 = StringPlay.areHalvesEqual(str);

main() should output these 3 results with descriptive text. The user should then be prompted with "Run again (y/n)" and the program rerun if wanted.
