Thoughts on replacing strings in java advanced

Thoughts on string replacement in advanced java-general Linux technology-Linux programming and kernel information. The following is a detailed description. The replacement of strings was recently used in the development process. I thought it was quite simple, but it could not be solved. The string is obviously replaced, but it cannot output the correct results. It is very depressing. Why?

Let's take a look at my code:

CODE: Newsdetials nt = (Newsdetials) ntIter. next (); System. out. println ("News details" + nt ); String content = nt. getContent (); System. out. println ("The news content is:" + content ); // Double quotation marks in the conversion string are single quotation marks Content. replaceAll ("\"","'"); System. out. println ("the replaced character is:" + content );
