Java int to char conversion with examples

In the last tutorial, we have discussed char to int conversion. In this guide, we will see how to convert an int to a char with the help of examples.

Java int to char conversion example

To convert a higher data type to lower data type, we need to do typecasting. Since int is higher data type (4 bytes) than char (2 bytes) so we need to explicitly typecast the int for the conversion.

//implicit type casting - automatic conversion
char ch = 'A'; // 2 bytes
int num = ch; // 2 bytes to 4 bytes

/* explicit type casting - no automatic conversion
 * because converting higher data type to lower data type
 */
int num = 100; //4 bytes
char ch = (char)num; //4 bytes to 2 bytes

Lets take an example.

In the following example we have an integer number num with the value 70 and we are converting it into a char by doing typecasting.

public class JavaExample{  
   public static void main(String args[]){  
	//integer number
	int num = 70;
		
	//type casting
	char ch = (char)num;  
	System.out.println(ch);  
   }
}

Output:
