import java.util.*;
class Readfile
{
public static void main(String[] args)
{
try
{
String str = "Readfile";
Reader reader = new StringReader(str);
int ch;
ch = reader.read();
System.out.println("\nInteger value " + "of character read: " + ch);
System.out.println("Actual" + "character read: " + (char)ch);
reader.close();
}
catch (Exception e)
{
System.out.println(e);
}
}
}
Output:
Integer value of character read: 82
Actualcharacter read: R
