Question

I already tried with string.equal function which will compare two strings, but what will be optimize way of doing same. Suggestions are welcome.

Hi all got it may help others What's the quickest way to compare strings in Java? Thanks Saurabh for sharing link.

*what will be optimize way of doing same* - `equals()` is the right way. You should choose what is right over what is fast. — TheLostMind, May 02 '16 at 06:31
.equalsIgnorecase is also a function to compare Strings, same as .equals but it is case sensitive. — Rakshit Nawani, May 02 '16 at 06:34

If you've identified through profiling that string comparison is a bottleneck, an optimized way of doing it is to **not** do it: map the strings to numbers or bools or enums or etc. elsewhere, or compare strings less frequently somehow. — Todd Christensen, May 03 '16 at 00:26

According to me, You should use the equals() method of the String class to compare Strings.

if (xyz.equals("something")) { 
    //Do what you want if string is equal... 
}
