java compare strings alphabetically

1String a = "HYRE"; 
2String b = "AGNYG";

4int compare = a.compareTo(b);

6if (compare < 0) {  
7    //a is smaller
8}
9else if (compare > 0) {
10    //a is larger

3[Äbc, äbc, Àbc, àbc, Abc, abc, ABC] Primary
4[Abc, abc, ABC, Àbc, àbc, Äbc, äbc] Secondary
5[abc, Abc, ABC, àbc, Àbc, äbc, Äbc] Tertiary
6

8[cache, CACHE, Cache] - Original Data
9[cache, CACHE, Cache] Primary
10[cache, CACHE, Cache] Secondary
11[cache, Cache, CACHE] Tertiary
12
