Examples of java.text.ParsePosition

java.text.ParsePosition
ParsePosition is a simple class used by Format and its subclasses to keep track of the current position during parsing. The parseObject method in the various Format classes requires a ParsePosition object as an argument.
By design, as you parse through a string with different formats, you can use the same ParsePosition, since the index parameter records the current position. @version 1.20 11/17/05 @author Mark Davis @see java.text.Format
