Find longest word in string

Here given code implementation process.

// Java program
// Find longest word in string
class MyString
{
	//Find the longest word in a string
	public String longest_word(String str_data)
	{
		String auxiliary = "";
		String result = "";
		//Loop contolling variables
		int i = 0, j = 0;
		System.out.print("\nGiven String : [" + str_data + "]\n");
		//Loop which is iterate given string character elements
		for (i = 0; i < str_data.length(); i++)
		{
			if (str_data.charAt(i) != ' ')
			{
				//reset variable
				auxiliary = "";
				//loop, combine string text
				for (j = i; j < str_data.length(); j++)
				{
					//Check that given character is space character or not
					if (str_data.charAt(j) != ' ')
					{
						//When not get space
						auxiliary = auxiliary + str_data.charAt(j);
					}
					else
					{
						//When find space break this loop 
						break;
					}
				}
				if (auxiliary.length() > result.length())
				{
					result = auxiliary;
				}
				i = j;
			}
		}
		return result;
	}
	public static void main(String[] args)
	{
		MyString obj = new MyString();
		// Simple case
		String result = obj.longest_word("This is wrong logic");
		System.out.print(" Longest Word : " + result + "\n");
		result = obj.longest_word("This is very dangerous error");
		System.out.print(" Longest Word : " + result + "\n");
