Char Array ib Java?

Feb 18th, 2009

Hi,

Can we declare Char Array in Java instead of String Arrays? So we can manipulate them? or we have to use Strings and then use charAt() method for it?

Thanks

Of course you can declare char arrays, but be aware that each "String" is a char array, so you would need a two dimensional array to hold char arrays equivalent to an array of Strings.

That depends on what you mean by "manipulate".

where lies the problem? in declaring the array and filling it?
