How would I sort a file like this below using java to meet the following
requirement without implementing Comparator?
sort the lines in the file alphanumerically, (1) ignoring (but keeping) non-alphanumeric characters, (2) with numbers preceding letters, and (3) with capital letters preceding lowercase letters (i.e., 0-9, A-Z, a-z). Any line containing only non-alphanumeric characters is removed.
For example:
input:
Hello
Beatrice
albert
@#$%
#%Albert
--''--911
hello
output:
1 --''--911
2 #%Albert
3 Beatrice
4 Hello
5 albert
6 hello
