Question

I am trying to remove the last character from a string, if it is a /. I am using a string array, temp[], to store the strings.

Here’s my code:

char ch = ' ';
for (int st = 0; st < temp.length; st++)
{
    ch = temp[st].charAt(temp[st].length()-1);
    if (ch == '/')
        temp[st] = temp[st].substring(0, temp[st].length()-1);
    result2.append(temp[st]);
}

but i am getting

StringIndexOutOfBoundsException -1

What am I doing wrong?

If you have empty String "" then temp[st].length()-1 == -1
