Java Character forDigit() Method

The forDigit(int digit, int radix) method of character class determines the character representation for a specific digit in the specified radix. If the value of the digit is not a valid digit in the specified radix or if the value of the radix is not a valid radix then a null character is returned. If the digit is less than 10, the '0'+digit is returned. Otherwise, the value 'a'+digit-10 is returned.

Syntax

Parameter

The above method requires two parameters:

The digit that needs to be converted to a character.

The radix

Return Value

The forDigit(int digit, int radix) method returns the char representation of the specified digit in the specified index.

Example 1

public class JavaCharacterforDigitExample1 {
    public static void main(String[] args) {
	 int a1 = 5;
	 int a2 = 6;
       char ch1 = Character.forDigit(a1, 10);
	char ch2 = Character.forDigit(a2, 16);
String str1 = "The char representation of " + a1 + " in radix 10 is " + ch1; String str2 = "The char representation 
of " + a2 + " in radix 16 is " + ch2; System.out.println( str1);
System.out.println( str2 );
	   }
	}

Test it Now

Output:

The char representation of 5 in radix 10 is 5
The char representation of 6 in radix 16 is 6

Example 2

public class JavaCharacterforDigitExample2 {
    public static void main(String[] args) {
        int a1 = 5;
        int a2 = 15;
        int a3 = 27;
        char ch1 = Character.forDigit(a1, 10);
        char ch2 = Character.forDigit(a2, 16);
        char ch3 = Character.forDigit(a3, 34);
        String str1 = "The char representation of " + a1 + " in radix 10 is " + ch1;
        String str2 = "The char representation of " + a2 + " in radix 16 is " + ch2;
        String str3 = "The char representation of " + a3 + " in radix 16 is " + ch3;
        System.out.println( str1 );
        System.out.println( str2 );
        System.out.println( str3 );
     }
  }

Test it Now

Output:

The char representation of 5 in radix 10 is 5
The char representation of 15 in radix 16 is f
The char representation of 27 in radix 16 is r

Example 3

import java.util.Scanner;
public class JavaCharacterforDigitExample3 {
     public static void main(String[] args) {
	 // Ask the user for the input
	    System.out.print("Enter an input:");
	    Scanner s = new Scanner(System.in);
	    int digit = s.nextInt();
	  // Ask the user for the radix
	    System.out.print("Enter the radix:");
	     int radix = s.nextInt();
	     char result = Character.forDigit(digit, radix);
  System.out.println("The character representation using radix \'" + radix + "\' for digit " + digit + "  is : " + result);
	         }
	}

Output:

Enter an input:4
Enter the radix:7
The character representation using radix '7' for digit 4  is : 4
