分割连接字符串

/*
 * Problem: Split and Join Strings using Java Streams
 * Given a string with words separated by spaces, write a function that splits the string into words and then joins them back together with a different delimiter using Java Streams.
 * 
 * Solution:
 * 1. Split the input string by spaces to get a stream of words.
 * 2. Use the Collectors.joining method to join the words with the new delimiter.
 * 3. Return the resulting string.
