How to check if a char in the string is '?

Question

I'm trying to implement a CSV parser. Suppose I have an input string "a, a'b, c, d'c, b", and output should be a list of strings: "a", "a'b, c, d'c", "b". So basically it means all chars between ''should be a part of one string. The problem I am facing is that when I scan the input string, I cannot check if the char is ', because if(c==''') is invalid, because 'is an invalid character constant. So how should I check if a char in the input string is '?

There is an open source library that already does this called opencsv. You can use it directly or get the code from here.

You need to escape the special character ' with a \. Take a look at the java documentation for more information.

b should be equal to true after executing this:

Character charValue = '\'';
boolean b = (charValue == '\'');
