How to get the length of a String Array?

coinscoins Posts: 13Member
I want use a loop to output the content of a String Array like
[code]
String[] NameList;
...
for(i=0;i<[red]n[/red];i++)
{
System.out.println(NameList[i]);
}
[/code]
but my problem is I don't know how many elements are there
in this array, I don't know how to get the value [red]n[/red].
Any thought will be appreciated.

    Arrays have a "property" called length. Here's how to use it:
    [code]
    for(i=0;i<NameList.length;i++)
    [/code]
    Help = (Throwable.getStackTrace() == null || SourceCode == null) ? null : getHelp(e, SourceCode);
