- What is the difference between String[] and String. . . in Java?
What's actually the difference between String[] and String if any? The convention is to use String[] as the main method parameter, but using String works too, since when you use varargs you can call the method in the same way you call a method with an array as parameter and the parameter itself will be an array inside the method body

You can always write it like this String[] errorSoon = {"Hello","World"}; For (int x=0;x<errorSoon length;x++) in this way u create a for loop that would like display the elements which are inside the array errorSoon oh errorSoon length is the same as errorSoon<2 { System out println(" "+errorSoon[x]); this will output those two words, at the top hello and world at the bottom of hello
- What does ${} (dollar sign and curly braces) mean in a string in . . .
Functionally, it looks like it allows you to nest a variable inside a string without doing concatenation using the + operator I'm looking for documentation on this feature I'm looking for documentation on this feature

@gimel: Actually, [:] on an immutable type doesn't make a copy at all While mysequence[:] is mostly harmless when mysequence is an immutable type like str, tuple, bytes (Py3) or unicode (Py2), a = b[:] is equivalent to a = b, it just wastes a little time dispatching the slicing byte codes which the object responds to by returning itself since it's pointless to shallow copy when, aside from
- What is the difference between String and string in C#?

- Differences between C++ string == and compare ()?
Internally, string::operator==() is using string::compare() Please refer to: CPlusPlus - string::operator==() I wrote a small application to compare the performance, and apparently if you compile and run your code on debug environment the string::compare() is slightly faster than string::operator==()
