Converting String Array -- String

Question

Hi All,
I am converting String array to string using the following code:
String[] a= ....;
StringBuffer result = new StringBuffer();
if (a.length > 0) {
result.append(a[0]);
for (int i=1; i<a.length; i++) {
result.append(a);
return result.toString();
Is there is any other easy or efficient way to convert rather than the above code ?
Thanks,
J.Kathir

It could have been written:
StringBuffer result = new StringBuffer();
for(int i=0; i<a.length; ++ i)
    result.append(a);
return result.toString();
Or in 1.5 lingo
StringBuilder result = new StringBuilder(); //slightly less overhead
for(String s : a)
    result.append(s);
return result.toString();If you aren't picky about the format of the resulting string,
you could use the java.utilArrays method )]toString(Object[]):
String[] array= {"Hello", "World", "this", "is", "a", "1.5", "method"};
String s = Arrays.toString(array); //[Hello, World, this, is, a, 1.5, method]
