Code Examples
#1 Code Example- Java Program to Convert char to int
Code -
Java Programming
class Main {
public static void main(String[] args) {
// create char variables
char a = '5';
char b = 'c';
// convert char variables to int
// ASCII value of characters is assigned
int num1 = a;
int num2 = b;
// print the values
System.out.println(num1); // 53
System.out.println(num2); // 99
}

#2 Code Example- char to int using getNumericValue() method
Code -
Java Programming
class Main {
public static void main(String[] args) {
// create char variables
char a = '5';
char b = '9';
// convert char variables to int
// Use getNumericValue()
int num1 = Character.getNumericValue(a);
int num2 = Character.getNumericValue(b);
// print the numeric value of characters
System.out.println(num1); // 5
System.out.println(num2); // 9
}

#3 Code Example- char to int using parseInt() method
Code -
Java Programming
class Main {
public static void main(String[] args) {
// create char variables
char a = '5';
char b = '9';
// convert char variables to int
// Use parseInt()
int num1 = Integer.parseInt(String.valueOf(a));
int num2 = Integer.parseInt(String.valueOf(b));
// print numeric value
System.out.println(num1); // 5
System.out.println(num2); // 9

#4 Code Example- char to int by subtracting with '0'
Code -
Java Programming
class Main {
public static void main(String[] args) {
// create char variables
char a = '9';
char b = '3';
// convert char variables to int
// by subtracting with char 0
int num1 = a - '0';
int num2 = b - '0';
// print numeric value
System.out.println(num1); // 9
System.out.println(num2); // 3
