Creating a shift cipher in Java

Question

I want to create an applet where a user can enter a sentance then enter a shift and then the program incrypts the sentance using java. Any help?

im new to java

Answer 1

First, look into how simple shift ciphers work. Second - assuming that your users only can enter common English characters - study the ASCII character codes. Third, do the math ;-)

Answer 2

I suggest reading a tutorial on applets in java, creating your applet and then reading more about ciphers and writing the encryption part of your program.
