Java Convert int to char

We can convert int to char in Java using typecasting. To convert higher data type into lower, we need to perform typecasting. Here, the ASCII character of integer value will be stored in the char variable.

To get the actual value in char variable, you can add '0' with int variable. Alternatively, you can use Character.forDigit() method.

Java int to char Example: Typecasting

Let's see the simple code to convert long to int into Java.

public class IntToCharExample1{
public static void main(String args[]){
int a=65;
char c=(char)a;
System.out.println(a);
}}

Test it Now

Output:

But if you store 1, it will store ASCII character of given number which is start of heading which is not printable. So it will not print anything on the console.

public class IntToCharExample2{
public static void main(String args[]){
int a=1;  
char c=(char)a;  
System.out.println(c);
}}

Test it Now

Output:

If you add '0' with int variable, it will return actual value in the char variable. The ASCII value of '0' is 48. So, if you add 1 with 48, it becomes 49 which is equal to 1. The ASCII character of 49 is 1.

public class IntToCharExample3{
public static void main(String args[]){
int a=1;  
char c=(char)(a+'0');  
System.out.println(c); 
}}

Test it Now

Output:

If you store integer value in a single quote, it will store actual character in char variable.

public class IntToCharExample4{
public static void main(String args[]){
int a='1';  
char c=(char)a;  
System.out.println(c);
}}

Test it Now

Output:

Java int to char Example: Character.forDigit()

To get the actual value, you can also use Character.forDigit() method.

public class IntToCharExample5{
public static void main(String args[]){
int REDIX=10;//redix 10 is for decimal number, for hexa use redix 16
int a=1;  
char c=Character.forDigit(a,REDIX);  
System.out.println(c); 
}}

Test it Now

Output:

To get the hexa value, use redix 16 in Character.forDigit() method.

public class IntToCharExample6{
public static void main(String args[]){
int REDIX=16;//redix 16 is for Hexadecimal value
int a=10;  
char c=Character.forDigit(a,REDIX);  
System.out.println(c); 
}}

Test it Now

Output:

As you can see in the output, the hexadecimal code of 10 is a.
