Write a java program to find ASCII value of a char || From A-Z || From a-z

char is a primitive data type in Java. Here in this tutorial, we will see What is the char in Java how can we find ASCII value of a char.

Char in Java

The Java char is a primitive data type. It is used to declare a type of character variables and a method. In Java Char can hold unsigned 16-bit Unicode characters with the range between 0 to 65,535 (inclusive).

Key Point in about Char in Java

  • The char range lies between 0 to 65,535 (inclusive).
  • Its default value of char in java is ‘\u0000’.
  • char size in Java is 2 byte.
  • It is used to store characters.

Find the ASCII value of a char in Java.

It’s really simple to find the ASCII value of a char in Java. We just need to convert the char into int. What is mean let’s try to understand by an example? We have a char ch = ‘A’. Here ch is a variable that holds a char  ‘A’. Now if we change the type of char ‘A’ char to int then it will print an ASCII value of the char.

char ch = 'A';
int n = ch;
System.out.println("Ascii Value of "+ch+" will be "+n);

Find ASCII value in Java from A-Z

In this example, we will find ASCII value-form A-Z. So to solve this problem the will follow two main step

  1. Convert the char into int.
  2. Run a loop from A-Z.
package com.demo;

import java.util.*;

 class Main  {   

    public static void main(String[] args) {      

       char CapitalChar = 'A';

       char SmallChar = 'a';

        //Find the ASCII Value from A-Z     

       System.out.println("ASCII Value from 'A' to 'Z'");

       for(int i ='A'; i<='Z'; i++) {

           System.out.println(CapitalChar +" : "+i);

           CapitalChar++;

       }  


    }

}

Find ASCII value in Java from a-z

System.out.println("ASCII Value from 'a' to 'z'");

        //Find the ASCII Value from a-z

       for(int i ='a'; i<='z'; i++) {

           System.out.println(SmallChar +" : "+i);

           SmallChar++;

       }

Find ASCII value of a char in java

package com.demo;

import java.util.*;

 class Main  {

    public static void main(String[] args) { 

       char Char= 'A';

       System.out.println(Char+0);

    }

}
