In this post, you will learn about finding and displaying ASCII value for any character. The American Standard Code for Information Interchange (ASCII) is a widely used character encoding scheme that assigns unique numeric values to various characters. In this blog post, we will delve into a simple Java program that allows you to find the ASCII value of a character.
Understanding ASCII:
ASCII represents characters using a 7-bit binary code, allowing a total of 128 unique characters to be encoded. The encoding assigns each character a numeric value between 0 and 127. Common ASCII values include alphabets (both uppercase and lowercase), digits, punctuation marks, and control characters.
Java Program to Find ASCII Value:
Let’s dive into the Java program that helps us find the ASCII value of a character. Here’s the code:
import java.util.Scanner;
public class ASCIIValueFinder {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter a character: ");
char ch = scanner.next().charAt(0);
int asciiValue = (int) ch;
System.out.println("The ASCII value of " + ch + " is " + asciiValue);
}
}
compile and run it. When prompted, enter a character of your choice. The program will then display the corresponding ASCII value.
Enter a character: A
The ASCII value of A is 65
Explanation:
- We begin by importing the
java.util.Scanner
class, which allows us to read input from the user. - In the
main
method, we create a newScanner
object to capture user input. - We prompt the user to enter a character using the
System.out.print
statement. - The next line of code
char ch = scanner.next().charAt(0);
reads a string input from the user and retrieves the first character using thecharAt(0)
method. We store this character in the variablech
. - To find the ASCII value, we cast the character
ch
to an integer using(int) ch
and assign the result to the variableasciiValue
. - Finally, we display the ASCII value to the user using the
System.out.println
statement.
In this blog post, we explored a simple Java program that allows us to find the ASCII value of a character. Understanding ASCII values is essential in various scenarios, such as working with character-based algorithms, encryption techniques, and networking protocols. By implementing this program, you have gained a valuable tool for exploring the world of character encoding in Java. Remember to experiment further and build upon this foundation to enhance your programming skills. Happy coding!
