0.1 float is greater than 0.1 double. I expected it to be false [duplicate]
...
I'd say the answer depends on the rounding mode when converting the double to float. float has 24 binary bits of precision, and double has 53. In binary, 0.1 is:
0.1₁₀ = 0.0001100110011001100110011001100110011001100110011…₂

Preferred way to create a Scala list
... = Vector(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
You probably don't even need to convert to a list in most cases :)
The indexed seq will have everything you need:
That is, you can now work on that IndexedSeq:
scala> list.foldLeft(0)(_+_)

Why the switch statement cannot be applied on strings?
...cpp/cpp_mfc/article.php/c4067/Switch-on-Strings-in-C.htm
Uses two maps to convert between the strings and the class enum (better than plain enum because its values are scoped inside it, and reverse lookup for nice error messages).
The use of static in the codeguru code is possible with compiler su...

How can I pad a String in Java?
...
Something simple:
The value should be a string. convert it to string, if it's not. Like "" + 123 or Integer.toString(123)
// let's assume value holds the String we want to pad
String value = "123";
Substring start from the value length char index until end length of pad...
