Java string sort Chinese + digit

idea: In Java, the sort needs to be overwritten by the Equals method and the public int compareTo (T o) of the comparable<t> interface;

Steps:

1. Use regular expressions to judge numbers, multiple consecutive numbers as a group,

2. Once a digital combination is retrieved,

3. Check out the next set of numbers and, if so, go to step 4, or go to step 6.

4. If the two sets of numbers appear equal, and the strings in the previous section are equal, enter step 5th. Otherwise break, skip to step 6th.

5. If the string in the previous section is exactly the same. Compares the size of two digits and, if the size is the same, goes to the next group, which is step 3. If the size is inconsistent, you can compare it to the size and end the comparison.

6. Call the CompareTo method of string, and the disease returns (the process ends).
The complete code is as follows:
