How to Print ASCII Values, Next and Preceding Characters in Java
When working with character manipulation in Java, a common requirement is to print the ASCII values of characters, as well as identify their subsequent and preceding characters. This guide covers how you can easily achieve this with straightforward Java code.
Understanding ASCII Values
ASCII (American Standard Code for Information Interchange) values are numerical representations of characters. Each character (such as letters, digits, and symbols) is assigned a unique ASCII code. For example, the ASCII value for 'A' is 65, while 'a' is 97.
Printing ASCII Values
To determine and print the ASCII value of a character, you can use the int type conversion in Java. Here’s a simple example:

When you run this code, it will prompt the user to enter a character and print the corresponding ASCII value, next character, and preceding character.
Conclusion
By leveraging Java's type casting and simple arithmetic operations, you can efficiently print the ASCII values, next characters, and preceding characters of any given input. This knowledge can be useful in various applications such as encryption, data processing, and encoding tasks.
