Comparing Strings compareTo in java

Question

I'm trying to check if a string alphabetically fits between two other strings. At the moment i'm doing it like this:

if(_subSize.compareTo("440/65") > 0 && "600/65".compareTo(_subSize) < 0){
    //fits in
} else { // fits not in between }

But when I have as _subSize = "440/65"; the if statement gets in the else. I've fixed that like this:

if(_subSize.compareTo("440/65") >= 0 && "600/65".compareTo(_subSize) <= 0){
    //fits in
} else { // fits not in between }

now the first statement is true. Yet the 2nd statement is false. How to get the 2nd statement to be true aswell? as "440/65" alphabetically comes before "600/65" so technically it should be lower or equals to 0. But somehow it's not working.

And i need the strings to be as string. They are no digits or something.

Answer 1

The 2nd .compareTo() is inverted related to the first one. You just need to have both to compare from the same perspective as follows:

if(_subSize.compareTo("440/65") >= 0 && _subSize.compareTo("600/65") <= 0){
    //fits in
} else { // fits not in between }
