findCharacterFromASCII()

Step 1: Understanding the problem

First of all, in order to find a character from an ASCII value, we need to understand what ASCII is. ASCII stands for American Standard Code for Information Interchange. It is a representation of text in computers. Every character in your keyboard can be assigned to a number between 32 and 126 - this number is known as a Character's ASCII value. In Java, to convert an ASCII value into a character, we can use type casting.

int ascii = 65;
char character = (char) ascii;
System.out.println(character);

Step 2: Defining the function

We'll define a function that takes an integer as a parameter. This integer will be the ASCII value which we want to convert to a character.

public static char asciiToChar(int ascii) {
    // Soon to be implemented
}

Step 3: Applying logic into the method

Simply casting the integer to a char should give us the character represented by that ASCII value. We use a return statement to send this character out of the function.

public static char asciiToChar(int ascii) {
    return (char) ascii;
}

Step 4: Testing the function

Now our function is ready to be tested. We can call this function with an ASCII value and print the returned result.

public static void main(String[] args) {
    char character = asciiToChar(65);
    System.out.println(character);
}

Conclusion

In this tutorial, we have created a simple function in Java that can convert an ASCII value into a character. Here is the full function:

public class Main {
    public static char asciiToChar(int ascii) {
        return (char) ascii;
    }

    public static void main(String[] args) {
        char character = asciiToChar(65);
        System.out.println(character);
    }
}

This function will convert given ASCII value to Char and print it out.
