The parseObject() method of java.text.MessageFormat class is used to parse the string object starting from the passed parse position in the parseObject() method.
Syntax:
public Object parseObject(String source, ParsePosition pos)
Parameter: This method takes the following arguments as parameter.
- source :- string over which parsing is going to perform.
- pos :- it is the starting index of parsing.
Return Value: This method returns array of object as an output.
Exception: This method throws NullPointerException if the parse position is null.
Below are the examples to illustrate the parseObject() method:
Example 1:
Java
// Java program to demonstrate // parseObject() method import java.text.*; import java.util.*; import java.io.*; public class GFG { public static void main(String[] argv) { try { // creating and initializing MessageFormat MessageFormat mf = new MessageFormat( "{0, number, #}, {2, number, #.#}, {1, number, #.##}" ); // creating and initializing String source String str = "10.456, 20.325, 30.444" ; // creating and initializing ParsePosition ParsePosition pos = new ParsePosition( 0 ); // parsing the string starting from pos // according to MessageFormat // using parseObject() method Object[] hash = (Object[])mf.parseObject(str, pos); // display the result System.out.println( "Parsed value are :" ); for ( int i = 0 ; i < hash.length; i++) System.out.println(hash[i]); } catch (NullPointerException e) { System.out.println( "Parse position is Null" ); System.out.println( "Exception thrown : " + e); } } } |
Parsed value are : 10.456 30.444 20.325
Example 2:
Java
// Java program to demonstrate // parseObject() method import java.text.*; import java.util.*; import java.io.*; public class GFG { public static void main(String[] argv) { try { // creating and initializing MessageFormat MessageFormat mf = new MessageFormat( "{0, number, #}, {2, number, #.#}, {1, number, #.##}" ); // creating and initializing String source String str = "10.456, 20.325, 30.444" ; // creating and initializing ParsePosition // ParsePosition pos = new ParsePosition(0); // parsing the string starting from pos // according to MessageFormat // using parseObject() method Object[] hash = (Object[])mf.parseObject(str, null ); // display the result System.out.println( "Parsed value are :" ); for ( int i = 0 ; i < hash.length; i++) System.out.println(hash[i]); } catch (NullPointerException e) { System.out.println( "Parse position is Null" ); System.out.println( "Exception thrown : " + e); } } } |
Parse position is Null Exception thrown : java.lang.NullPointerException
