Reverse string using recursion in scala

Scala program for Reverse string using recursion. Here problem description and explanation.

// Reverse string using recursion in Scala
class ReverseString()
{
	// This is reversing the string elements recursively
	def reverseText(text: String, location: Int): String = {
		// Base condition to stop the recursion process
		if (location >= 0)
		{
			// Recursive function call
			return text.charAt(location).toString() + 
              reverseText(text, location - 1);
		}
		// When no character remaining
		return "";
	}
	// This is handling the request process of reverse string elements
	def reverse(text: String): String = {
		// Display given string elements
		println("Before Text : [" + text + "]");
		return reverseText(text, text.length() - 1);
	}
}
object Main
{
	def main(args: Array[String]): Unit = {
		var task: ReverseString = new ReverseString();
		var text: String = "ABCDE";
		text = task.reverse(text);
		// After reverse	
		println("After Text  : [" + text + "]\n");
		text = task.reverse("654A321");
		// After reverse	
		println("After Text  : [" + text + "]\n");
	}
}

Output

Before Text : [ABCDE]
After Text  : [EDCBA]

Before Text : [654A321]
After Text  : [123A456]
