Concatenate Strings Varargs Delimiter in Java

Write a Java program using a method with varargs that concatenates a set of strings with a specified delimiter

The StringConcatenator class contains a static method named concatenateStrings that takes a delimiter and a variable number of strings (String... strings) as arguments.
Inside the method, it prints the given strings using Arrays.toString() to display the array contents.
It initializes a StringBuilder named result to build the concatenated string.
It then iterates through each string in the strings array.
For each string, it appends it to the result.
If it's not the last string, it appends the specified delimiter after the string.
After iterating through all strings, it returns the concatenated string.
In the main method, the concatenateStrings method is called with a hyphen ("-") as the delimiter and several strings as arguments.
The concatenated string is then printed to the console.

Source Code

import java.util.Arrays;
public class StringConcatenator
{
	static String concatenateStrings(String delimiter, String... strings)
	{
		System.out.println("Given String : " + Arrays.toString(strings));
		StringBuilder result = new StringBuilder();
		for (int i = 0; i < strings.length; i++)
		{
			result.append(strings[i]);
			if (i < strings.length - 1)
			{
				result.append(delimiter);
			}
		}
		return result.toString();
	}
 
	public static void main(String[] args)
	{
		String concatenatedString = concatenateStrings("-", "Pink", "Blue", "White", "Red", "Black", "Green", "Yellow");
		System.out.println("Concatenated String : " + concatenatedString);
	}
}

Output

Given String : [Pink, Blue, White, Red, Black, Green, Yellow]
Concatenated String : Pink-Blue-White-Red-Black-Green-Yellow
