How to convert Java char to int

In Java, a char value can be converted into int using by the following ways

• Directly assigning char value to int where the ASCII value of the character will be returned.

• Using Character.getNumericValue(char) method

• Using String.valueOf(char) method

1. Getting ASCII Value

When a char value is directly assigned as an int it returns the integer ASCII value assigned to the char value.

Example 1:

Here, the ASCII value associated with the char variable is returned.

public class StudyTonight
{  
	public static void main(String args[])
	{  
		char c1 = 'm';  
		char c2 = 'M';  
		int n1 = c1;  
		int n2 = c2;  

		System.out.println("The equivalent ASCII value is " +n1);  
		System.out.println("The equivalent ASCII value is " +n2);     
	}
}

The equivalent ASCII value is 109
The equivalent ASCII value is 77

2. Character.getNumericValue() Method

The getNumericValue() method is a part of Character class that returns the numeric(int) value of the character holds.

Example 2:

Here, a int value assigned to the character is returned using the Character.getNumericValue() method.

public class StudyTonight
{  
	public static void main(String args[])
	{  
		char ch = '8';  
		int n = Character.getNumericValue(ch);  
		System.out.println("The int value is : " +n);  
	}
}

The int value is : 8

3. Integer.parseInt() method

The parseInt() method is a part of the Integer class and returns an int value of the specified object value.

Example 3:

Here, the char value is converted to string first then converted to integer by using parseInt() method. the integer value is returned to the specified character value.

public class StudyTonight
{  
	public static void main(String args[])
	{  
		char ch = '5';  
		int n = Integer.parseInt(String.valueOf(ch));  
		System.out.println("The integer value is " +n); 
	}
}

The integer value is 5
