java character to integer code example

Example 1: java get an int from a char

Example 2: converting char to int in java

public class JavaExample{  
   public static void main(String args[]){  
	char ch = '9';
		
	/* Since parseInt() method of Integer class accepts
   	 * String argument only, we must need to convert
	 * the char to String first using the String.valueOf()
	 * method and then we pass the String to the parseInt()
	 * method to convert the char to int
	 */
	int num = Integer.parseInt(String.valueOf(ch));
		
	System.out.println(num);
   }
}

Example 3: char to int

int n = Character.getNumericValue(char);

Example 4: java string to integer

String example = "1";
int converted = Integer.parseInt(example);

Example 5: java convert char to int
