MessageFormat parseObject() method in Java with Example
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
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
MessageFormat mf
= new MessageFormat( "{0, number, #}, {2, number, #.#}, {1, number, #.##}" );
String str = "10.456, 20.325, 30.444" ;
ParsePosition pos = new ParsePosition( 0 );
Object[] hash = (Object[])mf.parseObject(str, pos);
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);
}
}
}
|
Output:
Parsed value are :
10.456
30.444
20.325
Example 2:
Java
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
MessageFormat mf
= new MessageFormat( "{0, number, #}, {2, number, #.#}, {1, number, #.##}" );
String str = "10.456, 20.325, 30.444" ;
Object[] hash = (Object[])mf.parseObject(str, null );
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);
}
}
}

Output:
Parse position is Null
Exception thrown : java.lang.NullPointerException
