Characters

Objectives

1. Discuss Character Math.

Notes

• We can also do math on characters.
  • letter++;
  • (char) (letter + 1);
  • code = ch - 'a';
  • code = ch - '0';

• 
  import java.util.Scanner;
  
  public class CharDemo {
       public static void main(String[] args) {
  
          char ch = '\n';
          int code;
  
          ch = '7';
          code = ch - '0';
          System.out.printf("'%c' - '0' = %d\n", ch, code);
  
          ch = 'd';
          code = ch - 'a';
          System.out.printf("'%c' is %d from a\n",ch, code);
  
       }
  }
