I have list with different brackets:[,],{,},(,) I need to merge them into double brackets

for (int i = 0; i < word.size(); i++) {
        if (word.get(i).equals("("){
            word.set(i,"()");
        }
        if (word.get(i).equals("{"){
            word.set(i,"{}");
        }
        if (word.get(i).equals("["){
            word.set(i,"[]");
        }`

It works, but it remove some brackets. If before this there are like 107963, now it's 107952

I suggest you use a `switch(word.get(i))` statement. – Peter Lawrey Apr 06 '16 at 11:04

this code doesn't merge anything, it tries to replace an opening brackets with a pair of brackets (and fails due to wrong String comparison) and doesn't touch existing closing brackets – Eran Apr 06 '16 at 11:04
That's exactly why it doesn't work – Василий Богданец Apr 06 '16 at 11:07

@Peter Lawrey the question is not a duplicate of this http://stackoverflow.com/questions/513832/how-do-i-compare-strings-in-java – c0der Apr 06 '16 at 11:25
Use `if (word.get(i).equals "("){ word.set(i,"()"); }` – c0der Apr 06 '16 at 11:43
@OferYuval can the OP update the question to show how this is not because `==` instead of `equals` being used. – Peter Lawrey Apr 06 '16 at 12:06

It is not clear how you are counting the number of brackets. Please show a [mcve] – OneCricketeer Apr 06 '16 at 12:18

@Peter Lawrey I think what you are saying that "equal instead of ==" is the answer to the question asked. While this is a fair and good answer, the question asked is completely different from "How do I compare strings in Java? " . – c0der Apr 07 '16 at 10:11
