Hey guys,
I'm writing a method for an assignment for school and it needs to take an inputted char array and convert it into a string. Here is what I have but it doesn't execute. It compiles fine but gets a runtime error:

java.lang.ArrayIndexOutOfBoundsException: 5
at Tester.charArrayToString(Tester.java:43)

So really my question is this, how do I convert a char to a string so that I can add it together in the for loop? The method is listed below. Thanks a billion in advance!

(not sure if i have to put this in a quote or code block or something but here it is)

public String charArrayToString(char[] c)
{
String sS = "";

for(int b=0; b<=c.length; b++)
{
sS = sS + c ;
}
return sS;
}

can you do this?
String s = new String(c);

**EDIT**
Yup.

For future reference check the Java API. It's a fantastic resource

The error in the code was that the limit should be b < c.length, not b <= c.length. Array indices go from 0 -> length-1, not 1->length

Thank you very much! I'll try that.

EDIT: All I had to do was change that condition like you said. I'm a dummy, I knew that I just spaced out lol. Thanks again! It works now, without the need for that line. I think he wanted us to use a for loop but i'm going to try it as well with that String s = new String(c).

lol sorry, i know i shouldn't do that, i was just kind of impatient. childish i know

Creating an empty string and iteratively concatenating a single character will be painfully slow. Use java's constructor - it will be optimized.

Yeah, I ended up doing that, lol, 2 line method rather than a 6 line method, woot! I hope my prof accepts it, I included the original way I did it in a comment anyway so he can check it out. Thanks again! I didn't even know that Java API existed! This will definitely save me in future snags.

Yeah, The java site and API are the best places to find something if you need something or forget what a certain method does, etc.
