//marker 1 : charAt() java built in function that capture a character from a string 
               Syntax: char variable=string.charAt(position);
              Where  #string is any string from which you want to to capture the character
                       # position a numerical value or position of character in string

Note: java takes everything as String. In above program a[0] means 0th argument and charAt(0) means its first character always.


To run this program in Command Prompt :

C:\User>javac ascii.java
C:\User>java ascii h
