String Play (JAVA BEGINNER)

Implement the following methods:

// 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. (The name of the method is up to you.)

Use these methods to rewrite the corresponding parts of the attached StringPlay program.
