How to replace ' in a String in java?

Question

String str="India's";
str.replaceAll("'", "");

The above code in my opinion should replace all inverted single commas with nothing in the string.

But the in the output nothing changes.

Can anyone figure out what am I doing wrong?

Thanks

Answer 1

String is immutable, assign it to the same reference

str = str.replaceAll("'", "");

Answer 2

String is an immutable class, any change to an object of this class will result in a new object created. Method replaceAll is returning the updated String object. so you should do something like this:

str = str.replaceAll("'","");
