This site contains some content ( interview questions ) submitted by users.

Find the rate of change at a point on a polynomial How can I open the next/previous file alphabetically? http://www.java-forums.org/new-java/81830-error-type-mismatch-cannot-convert-java-lang-string-double.html What do I need to do to protect someone from stealing my website idea? For a more reasonable use of substring, use String.concat rather than letting the compiler louse it up: str.substring(i, i+1).concat(str.substring(j, j+1)) That, I believe, only produces two temporary String objects (but no Adding a char to a string results in another string.

Strings will share the char[]. weblink You could also use the String constructor: new String(new char[] { 'a', 'b'}) There are no other ways to perform this conversion directly [1]. (String)char seems logical, but isn't allowed. 1. It's worse than that, there are StringBuilders about.

I have no idea why javac produces such bad code, but that is what it does.
