Java/my notes

The Java programming language also supports a few special escape sequences for char and String literals: \b (backspace), \t (tab), \n (line feed), \f (form feed), \r (carriage return), \" (double quote), \' (single quote), and \\ (backslash).

Finally, there's also a special kind of literal called a class literal, formed by taking a type name and appending ".class"; for example, String.class. This refers to the object (of type Class) that represents the type itself.

int x4 = 5_______2; // OK (decimal literal)
int x6 = 0x_52; // Invalid; cannot put underscores at the beginning of a number
int x9 = 0_52; // OK (octal literal)
