## Class ParsePosition

- java.lang.Object
- - java.text.ParsePosition

-     public class ParsePosition
      extends Object

  `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.

- - ### Constructor Detail

    - #### ParsePosition

          public ParsePosition(int index)

      Create a new ParsePosition with the given initial index.

  - ### Method Detail

    - #### getIndex

          public int getIndex()

      Retrieve the current parse position. On input to a parse method, this is the index of the character at which parsing will begin; on output, it is the index of the character following the last character parsed.

    - #### setIndex

          public void setIndex(int index)

      Set the current parse position.

    - #### setErrorIndex

          public void setErrorIndex(int ei)

      Set the index at which a parse error occurred. Formatters should set this before returning an error code from their parseObject method. The default value is -1 if this is not set.
      Since:
        1.2

    - #### getErrorIndex

          public int getErrorIndex()

      Retrieve the index at which an error occurred, or -1 if the error index has not been set.
      Since:
        1.2

    - #### equals

          public boolean equals(Object obj)

      Overrides equals
      Overrides:
        `equals` in class `Object`
      Parameters:
        `obj` - the reference object with which to compare.
      Returns:
        `true` if this object is the same as the obj argument; `false` otherwise.
      See Also:
        `Object.hashCode()`, `HashMap`

    - #### hashCode

          public int hashCode()

      Returns a hash code for this ParsePosition.
      Overrides:
        `hashCode` in class `Object`
      Returns:
        a hash code value for this object
      See Also:
        `Object.equals(java.lang.Object)`, `System.identityHashCode(java.lang.Object)`

    - #### toString

          public String toString()

      Return a string representation of this ParsePosition.
      Overrides:
        `toString` in class `Object`
      Returns:
        a string representation of this object
