ParsePosition objects are passed to the parse( ) and parseObject( ) methods of Format and its subclasses. The ParsePosition class represents the position in a string at which parsing should begin or at which parsing stopped. Before calling a parse( ) method, you can specify the starting position of parsing by passing the desired index to the ParsePosition( ) constructor or by calling the setIndex( ) of an existing ParsePosition object. When parse( ) returns, you can determine where parsing ended by calling getIndex( ). When parsing multiple objects or values from a string, a single ParsePosition object can be used sequentially.

public class ParsePosition {
// Public Constructors
     public ParsePosition(int index);

1.2  public int getErrorIndex( );  
     public int getIndex( );  
1.2  public void setErrorIndex(int ei);  
     public void setIndex(int index);  
// Public Methods Overriding Object
1.2  public boolean equals(Object obj);  
1.2  public int hashCode( );  
1.2  public String toString( );
