Java String Concatenation: Joining Array Elements

import java.util.*;

public class Solution { public String join(String[] s) { String t = ''; for (String str : s) { t += str; } return t; } }

This code provides a simple solution to joining elements of a string array in Java. It uses a for loop to iterate through the array, concatenating each element to the 't' string. This approach is fundamental to working with strings and arrays in Java, making it a valuable example for understanding string manipulation.
