Why is Object[].class.isAssignableFrom(String[].class) == true , while String[].getSuperClass() or getGenericInterfaces() could not get Object[] ?
I checked the source of JDK, but i don't think i can get the answer myself. For now, I know JDK uses tree...

That should force CF to recognize it as a string rather than as a boolean..
I believe that your or any similar "string forcing" workaround is the only possible way to prevent = javacast("string", "yes") .

Together with preg_match :

Try this regular expression:
(?:^[^(]+|(?<=^\()[^\s)]+)
This will get you either anything up to the first parenthesis or the first word inside the first parenthesis .

Which is more efficient for the compiler and the best practice for checking whether a string is blank?
Checking whether the length of the string == 0 Checking whether the string is empty (strVar == "") Also, does the answer depend on language?

"" is a string literal so, in JavaYes, it depends on language, since string storage differs between languages.
@DerekPark: That's not always true.

I'm a C++ guy learning Java. I'm reading Effective Java and something confused me. It says never to write code like this:
String s = new String("silly");
Because it creates unnecessary String objects. But instead it should be written like this:

then s!=t (because you've explicitly created a new string) although s.equals(t) will return trueString s are special in Java - they're immutable, and string constants are automatically turned into String objects.

I have a variable of type string. I want to check if it contains a certain string. How would I do that?
Is there a function that returns true if the string is found, and false if it isn't?

How would you convert an array of booleans to a string like "false, true, true, false" - using as few lines of code as possible?
Python allows me to use the following (very nice and clean):
", ".join(map(str, [False, True, True, False]))
In C#, string...

A)
string s = "value"; string s1 = "value";
Do s and s1 reference variables point to same string object ( I’m assuming this due to the fact that strings are immutable )?
b) I realize equality operators ( ==, > etc ) have been redefined to compare the...

If you create a string programatically, you'd have to manually intern the string.
Yes, these will point to the same string, because they're both defined as string literals.
