Epsilon-transitions

(The two characters that label the transition into state q₃ are capital L and lower-case l).

The above automaton accepts strings that are legal Java integer literals, such as the strings:

There are several new features to this automaton. The epsilon (e-like symbol) labeling the transition out of the start state means that the transition can be made without consuming a character. This allows an optional "+" or "-" character at the beginning of the string.

There are two transitions out of state q₁ labeled with 0. This means that if the current character is 0 then either of these transitions can be used.
