java - Illegal Escape Character ""

Question

I want to get the name at the end of a link so I did that

if( invName.substring(j,k).equals("")){
                                 copyf=invName.substring(0,j);}

Eclipse said String literal is not properly closed by a double-quote

How can I compare String with this char ?

Answer 1

The character '' is a special character and needs to be escaped when used as part of a String, e.g., "". Here is an example of a string comparison using the '' character:

if (invName.substring(j,k).equals("")) {...}

You can also perform direct character comparisons using logic similar to the following:

if (invName.charAt(j) == '\') {...}
