Conversions

• java.lang provides classes to treat built-in types as Object references
  • Double and Integer for double and integer respectively
  • must be converted to built-in type to be used with arithmetic operators

    new Double(din.readLine()).doubleValue()
    

    • reads into a String
    • converts to a Double
    • extracts the double
• No equivalent of format conversions as in C's printf.
  • format method included to provide this functionality
  • Literal chars should be changed when subject to I18N
