And if i want compare 3 strings: for example: "kali, karkiv, karola" ? How can i do it at the same time? and how put in order in a list?

[@Appficial]

Use && for compound expressions. Then use arrays or ArrayList to store them in a list. I have videos on both

Question, sir: Could you use these methods to sort a 2D string array so that the array elements are sorted from A to Z? I have seen some videos related to this, but not exactly what I need. I have a project concerning this and for some reason, there is one piece that is giving me a bit of trouble.
This is some of the relevant code right here:
for(int i=0; i>numberOfRows; i++) {
if(statesCapitals[i].compareToIgnoreCase(statesCapitals[i-1]) > 0) {
temp = statesCapitals[i];
statesCapitals[i] = statesCapitals[i-1];
statesCapitals[i - 1] = temp;
}
My compareToIgnoreCase is giving me an error: Cannot invoke compareToIgnoreCase(String[]) on the array type String[].
I'm not exactly sure what's wrong with the code since both elements are strings. Any help would be appreciated! Thanks!

For a 2D array, you would loop through each element and sort it, since each element is also an array. Since you are working with Strings, you can just use the Comparator sort() method
