there are two Pattern as follows
String pattern1 = "A775[0-9A-Z]";
String pattern2 = "A7750|A7756"; how can I use java to determine that the matching range of pattern2 is within the range of pattern1?
Please take a look at it

if you have enough data sample strings, you can compare them with statistical ideas, that is, use these two patterns to match all samples, get two matching result sets, and then compare the result sets with set operations.
traditional methods are difficult to do, and such problems can be solved through in-depth learning and neural network models (you can try google's tensorflow). But there are two difficulties (actually manpower):
when there are enough samples and the model training reaches a certain level, the "network model" has the reasoning of judging whether pairwise regular expressions are included
.there is no easy way to do this, you must parse it yourself. But it's very difficult (it's okay if it's just your example, but it's very difficult if it's universal)
so to speak, it can't be done
