Java Program to Find the ASCII Value of a Character

In this Java tutorial, you’ll learn how to find the ascii value of a character using Java programming language.

ASCII Value (American Standard Code for Information Interchange) is a character that encoded standard for text files in computers. 

How to Find the ASCII value of a Character in Java?

In this program, we’ll learn how to print ASCII values or code through JAVA program. 

Example 1: 

public class Main   

{   

public static void main(String[] args)    

{   

char cha1 = 'a';   

char cha2 = 'S';   

char cha3 ='%'; 

int asciivalue1 = cha1;   

int asciivalue2 = cha2;  

int asciivalue3 = cha3;  

System.out.println("The ASCII value of " + cha1 + " is: " + asciivalue1);   

System.out.println("The ASCII value of " + cha2 + " is: " + asciivalue2);   

System.out.println("The ASCII value of " + cha3 + " is: " + asciivalue3); 

}   

}

Output 

The ASCII value of a is: 97 

The ASCII value of S is: 83 

The ASCII value of % is: 37

In the above program, we have declared three variables cha1, cha2, cha3 of type characters having the characters a, S and % respectively. 

To convert the variable into an int variable we cast char type to int type. 

Print the ASCII value using println function. 

Example 2: ASCII value from A TO ZExample 2: ASCII value from A TO  

public class Main 

{   

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

Using the loop statement, we can print all alphabets value from A to Z.
