Java Program to Convert int into char

May 26, 2023

What is int in Java ?

“int” is a primitive data type in Java that is used to represent integers (whole numbers) within a certain range of values. The range of values that can be stored by an “int” is from -2^31 to 2^31-1. The “int” data type is commonly used in mathematical operations and to represent arrays of integers.

What is char in Java ?

“char” is a primitive data type in Java used to represent a single character. A character in Java is specified using single quotes, e.g. ‘a’, ‘b’, ‘c’, etc. The “char” data type is often used to store characters and strings of text. Each character is stored as a 16-bit Unicode character, which allows for representation of a wide range of characters and symbols.

Steps to Convert int into char :

Step 1 : Declare an integer variable intValue .

Step 2 : Assign a value to intValue .

Step 3 : Declare a character variable charValue .

Step 4 : Cast intValue to char and assign the result to charValue

Pseudo Code for the above algorithm.

int intValue = 65;
char charValue;
charValue = (char) intValue;

Note : The above code assumes that the int value is within the valid range for a Unicode character (0 to 65,535). If the int value is outside this range, the code may produce unexpected results.

Example :

Run

public class Main {
  public static void main(String[] args) {
    int[] intValues = { 65, 66, 67, 68, 69 };

    for (int intValue : intValues) {
      char charValue = (char) intValue;
      System.out.println("The char value of " + intValue + " is: " + charValue);
    }
  }
}

Output :

The char value of 65 is: A
The char value of 66 is: B
The char value of 67 is: C
The char value of 68 is: D
The char value of 69 is: E

Explanation : In this example, the code first defines an array of int values and then iterates over each value, casting it to char using the typecast operator (char). The result of the cast is then printed to the console.

Example :

Run

class Main {
  public static void main(String[] args) {

    // create int variable
    int num = 97;

    // convert int to char using typecasting
    char ch = (char) num;

    // print value
    System.out.println(ch);    // a
  }
}

Output :

Explanation : In this example, an int variable num is created and assigned the value 97. The int value is then converted to a char by casting it to char. The resulting char value is stored in the char variable ch and printed to the console.

Example :

Run

class Main {
  public static void main(String[] args) {

    // create int variables
    int num1 = 33;
    int num2 = 64;
    int num3 = 35;
    int num4 = 97;

    // convert int to char using typecasting
    char symbol1 = (char) num1;
    char symbol2 = (char) num2;
    char symbol3 = (char) num3;
    char symbol4 = (char) num4;

    // print values
    System.out.println("The symbol for " + num1 + " is: " + symbol1);
    System.out.println("The symbol for " + num2 + " is: " + symbol2);
    System.out.println("The symbol for " + num3 + " is: " + symbol3);
    System.out.println("The symbol for " + num4 + " is: " + symbol4);
  }
}

Output :

The symbol for 33 is: !
The symbol for 64 is: @
The symbol for 35 is: #
The symbol for 97 is: a

Explanation : In this updated version, four int variables num1, num2, num3, and num4 are created and assigned values 33, 64, 35, and 97, respectively. Each int value is then converted to a char using typecasting, and the resulting char values are stored in char variables symbol1, symbol2, symbol3, and symbol4. The values of these char variables are then printed to the console along with their corresponding int values.
