How to compare two array list when one array list always fluctuate rows?

Question

I am creating one array list and attempting to equals to another array list, the reader through CSV file. CSV row is not in the same order, changing everything when downloading. I tried with equals and compare to but both fail due to row fluctuations. How do I compare? Apart from row number, everything is the same .

Answer 1

Have you tried sorting and comparing?

You can do,

Arrays.sort(Object[]);

E.g.

Array.sort(A1); //Say this is the array you got from CSV file.

Array.sort(B1); //This is your array you want to compare with.

Then do,

Arrays.equals(A1,B1);

Hope tha thelps!

One thing you can to is to check the each char at ith value then you can compare both of them
you can use for loop and then use equals method.
