The ASCII (American Standard Code for Information Interchange) is a 7-bit character set consisting of 128 characters ranging from 0 to 127. It assigns a numerical value to each character, representing its ASCII value. For example, the ASCII value of the character ‘A’ is 65.
In Java, there are two methods to print the ASCII value:
- Assigning a Variable to the int Variable
- Using Type-Casting
Assigning a Variable to the int Variable
In Java, the ASCII value of a character can be printed without using any specific method or class. Java automatically converts the character value to its corresponding ASCII value.
In the given program, the ASCII values of characters ‘a’ and ‘b’ are obtained by assigning them to integer variables asciivalue1 and asciivalue2, respectively. The ASCII values are then printed using System.out.println(). Here’s the rewritten content:
PrintAsciiValueExample1.java
public class PrintAsciiValueExample
{
public static void main(String[] args)
{
// character whose ASCII value to be found
char ch1 = 'a';
char ch2 = 'b';
// variable that stores the integer value of the character
int asciivalue1 = ch1;
int asciivalue2 = ch2;
System.out.println("The ASCII value of " + ch1 + " is: " + asciivalue1);
System.out.println("The ASCII value of " + ch2 + " is: " + asciivalue2);
}
}
Output:
The ASCII value of a is: 97 The ASCII value of b is: 98
PrintAsciiValueExample2.java
public class PrintAsciiValueExample1
{
public static void main(String[] String)
{
int ch1 = 'a';
int ch2 = 'b';
System.out.println("The ASCII value of a is: "+ch1);
System.out.println("The ASCII value of b is: "+ch2);
}
}
Output:
The ASCII value of a is: 97 The ASCII value of b is: 98
Similarly, we can print the ASCII value of other characters (A, B, C, …., Z) and symbols (!, @, $, *, etc.).
Using Type-Casting
Type-casting is a method used to convert a variable from one data type to another.
In the given program, variables ch1 and ch2 of type char are declared with the characters ‘a’ and ‘b’, respectively. The next two lines perform type-casting by converting the char type to int type using (int). This results in the conversion of ch1 and ch2 into int variables ascii1 and ascii2, respectively.
Finally, the values of ascii1 and ascii2 are printed, representing the ASCII values of the characters.
PrintAsciiValueExample3.java
public class PrintAsciiValueExample2
{
public static void main(String[] args)
{
//characters whose ASCII value to be found
char ch1 = 'a';
char ch2 = 'b';
//casting or converting a charter into int type
int ascii1 = (int) ch1;
int ascii2 = (int) ch2;
System.out.println("The ASCII value of " + ch1 + " is: " + ascii1);
System.out.println("The ASCII value of " + ch1 + " is: " + ascii2);
}
}
Output:
The ASCII value of a is: 97 The ASCII value of b is: 98
If we want to obtain a character from the user instead of assigning it directly.
PrintAsciiValueExample4.java
import java.util.Scanner;
public class PrintAsciiValueExample3
{
public static void main(String args[])
{
System.out.print("Enter a character: ");
Scanner sc = new Scanner(System.in);
char chr = sc.next().charAt(0);
int asciiValue = chr;
System.out.println("ASCII value of " +chr+ " is: "+asciiValue);
}
}
Output 1:
Enter a character: P ASCII value of P is: 80
Output 2:
Enter a character: G ASCII value of G is: 71
The following program prints the ASCII value of all characters (0 to 255). Here, we have shown a few sample values in the output.
AsciiValueOfAllChracters.java
public class AsciiValueOfAllChracters
{
public static void main(String[] args)
{
for(int i = 0; i <= 255; i++)
{
System.out.println(" The ASCII value of " + (char)i + " = " + i);
}
}
}

AsciiValueAtoZ.java
public class AsciiValueAtoZ
{
public static void main(String[] args)
{
for(int i = 65; i <= 90; i++)
{
System.out.println(" The ASCII value of " + (char)i + " = " + i);
}
}
}
Output:
The ASCII value of A = 65 The ASCII value of B = 66 The ASCII value of C = 67 The ASCII value of D = 68 The ASCII value of E = 69 The ASCII value of F = 70 The ASCII value of G = 71 The ASCII value of H = 72 The ASCII value of I = 73 The ASCII value of J = 74 The ASCII value of K = 75 The ASCII value of L = 76 The ASCII value of M = 77 The ASCII value of N = 78 The ASCII value of O = 79 The ASCII value of P = 80 The ASCII value of Q = 81 The ASCII value of R = 82 The ASCII value of S = 83 The ASCII value of T = 84 The ASCII value of U = 85 The ASCII value of V = 86 The ASCII value of W = 87 The ASCII value of X = 88 The ASCII value of Y = 89 The ASCII value of Z = 90
Similarly, we can print the ASCII value of lowercase alphabets (a to z) by modifying the loop in the above code.
for(int i = 97; i <= 122; i++)
