Java: how to initialize String[]? - Stack Overflow 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
c# - Whats does the dollar sign ($string) do? - Stack Overflow In String Interpolation, we simply prefix the string with a $ (much like we use the @ for verbatim strings) Then, we simply surround the expressions we want to interpolate with curly braces (i e { and }): It looks a lot like the String Format() placeholders, but instead of an index, it is the expression itself inside the curly braces
What is the difference between String and string in C#? System String is a type in the CLR When you use C# together with the CLR string will be mapped to System String Theoretically, you could implement a C#-compiler that generated Java bytecode A sensible implementation of this compiler would probably map string to java lang String in order to interoperate with the Java runtime library
How do I compare strings in Java? - Stack Overflow If you make a new string like String str = new String("Testing") you end up creating a new string in the cache even if the cache already contains a string having the same content In short "MyString" == new String("MyString") will always return false
How do I append one string to another in Python? If you only have one reference to a string and you concatenate another string to the end, CPython now special cases this and tries to extend the string in place The end result is that the operation is amortized O(n) e g s = "" for i in range(n): s += str(i) used to be O(n^2), but now it is O(n) More information From the source (bytesobject c):
difference between new String [] {} and new String [] in java 2 what is the diff between String array=new String[]; and String array=new String[]{}; The first won't compile for two reasons while the second won't compile for one reason The common reason is that the type of the variable array has to be an array type: String[] not just String

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==()
