Java reading a string from file not equal to itself

I am new to programming and I cannot for the life of me figure out why aa does not equal bb in the following. I need to extract a file path string from a text file of settings. I read in the 9th line from a txt file as a string like so to get the path:

String content = new Scanner(new File("settingsfilepath.txt")).useDelimiter("\\Z").next();
String[] textStr = content.split("\n");

aa = textStr[9];
bb = "testpath";

    if(aa.equals(bb)){
        print("Contents of both strings are same");
    }else{
        print("Contents of strings are different");
    }

print(textStr[9]);
print(bb);

OUTPUT when printing aa is: testpath

OUTPUT when printing bb is: testpath

RESULT: "Contents of strings are different"

I need the variable aa to equal the string bb because when I use a save function [savefunction(filetype,filepath);]

somesavefunction(filetype,aa); error problem with path

somesavefunction(filetype,bb); this works

Are there two different types of strings? Maybe I am not reading in the file path from the text file as a string properly? I feel so stupid :( I hope this question makes sense as I had a hard time trying to explain it in this post. Thanks for any and all help.

I doubt you have white space, try using trim() and change your condition to

aa.trim().equals(bb.trim())

Assuming the 9th line is what you want, you should set aa to the 8th array element as arrays have a zero-based index.

aa = textStr[8];

I recommend you do a

System.out.printf("aa = '%s', bb = '%s'%n", aa, bb);

I suspect there is white space in one or both strings.
