3.10 Literals

A literal is the source code representation of a value of a primitive type (�4.2), the String type (�4.3.3), or the null type (�4.1):
Literal:
IntegerLiteral
FloatingPointLiteral
BooleanLiteral
CharacterLiteral
StringLiteral
NullLiteral


An integer literal is of type long if it is suffixed with an ASCII letter L or l (ell); otherwise it is of type int (�4.2.1). The suffix L is preferred, because the letter l (ell) is often hard to distinguish from the digit 1 (one).
..
A floating-point literal is of type float if it is suffixed with an ASCII letter F or f; otherwise its type is double and it can optionally be suffixed with an ASCII letter D or d.
