How to compare 2 strings in batch

Question

I have this code
for /l %%a in (0, 1, 25) do (
if /i !TextAlphabet!==!Alphabet[%%a]! (
set AlphabetNumber=%%a
!Alphabet[]! is an array containing alphabets
I tried echoing !TextAlphabet! and !Alphabet[%%a]! and when they are the same,
%AlphabetNumber% is still the value I set before the loop
I tried checking for white spacesin my variables but found none

        set1.add(s1.nextToken());
    while(s2.hasMoreTokens())
        set2.add(s2.nextToken());
    for(Iterator it1=set1.iterator();it1.hasNext();)
        String temp1=it1.next().toString();
        for(Iterator it2=set2.iterator();it2.hasNext();)
            if(temp1.equals(it2.next().toString()))
                value.add(temp1);
    System.out.println(value);
