It seems there are different ways to read and write data of files in Java.
I want to read ASCII data from a file. What are the possible ways and their differences?
I have String name = "admin";
then I do String charValue = name.substring(0,1); //charValue="a"
I want to convert the charValue to its ASCII value (97), how can I do this in java?
I'm currently working on a Java project that is emitting the following warning when I compile:
/src/com/myco/apps/AppDBCore.java:439: warning: unmappable character for encoding UTF8
[javac] String copyright = "� 2003-2008 My Company. All rights reserved.";
I'm not sure …
