ASCII Characters in Java

Posted on 2001-06-09

I have a function that does a find a replace routine on a given string. ie.

replace(String Input, String Find, String Replace)

Therefore, I want to insert the double quote " symbol as the Find parameter in the Replace function and replace it with a "%" symbol. The only way I can think of solving this problem is sending in a ASCII Charater as the Find String. But how do I do this. Need code examples.

replace(input, "\"", "%");

objects, can you please explain what the \" means, I'm new to Java, but it worked. Is there a reference web sited I can look at that explains this technique? I assume it means its a double quote...etc. Thanks.

The back slash sort of says to ignore any special meaning for the next character, and to treat it purely as an ASCII character.
If I can think of a reference I'll forward it on to u.

Oops, ignore my previous definition it's only partly correct. I forgot about special escape sequences such as \t \n etc.
Have a look at the following articales which includes discussions of escape sequences:

And I'll leave the explanations to the experts and go back to just writing code :-)
