Java Removing leading$/$trailing whitespace Users may type or copy$-$paste in a text box of a web form, perhaps a name like "Joe Smith". The user sometimes has whitespace before or after the text, like $"$ Joe Smith $".$ A program typically strips such leading and trailing whitespace. Given a string, create a new string that lacks any leading or trailing spaces. Given $"$ Joe Smith $",$ the new string should be "Joe Smith". Be sure to handle the case of the user entering only whitespace, or entering nothing, which each should yield an empty string $"".$ Hints: Initially, try to find the index of the first non$-$space character. Set the index to $0,$ then use a while loop to check each character. Your while loop expression should first check that the index is valid for the size of the string. The size$()$ function of a string returns an unsigned int, so declare your index variable as an unsigned int so you can compare without a compiler warning. Next, try to find the index of the last non$-$space character. Use a different index variable. You while loop expression should first check that it is greater$-$than$-$or$-$equal to $0$ to ensure it is valid. Once you know the first and last non$-$space characters, you can use a for loop to copy those characters to the new string. After the first while loop, be sure to check if any non$-$space character was found $($by checking if the index is less than the string's last element$).$ If no non$-$space character was found, just return.
