Last Updated :
08 Oct, 2021
The parse() method of java.text.MessageFormat class is used to parse the string object from the beginning of the index.
Syntax:
public Object[] parse(String source)
throws ParseException
Parameter: This method takes string source as an argument over which parsing is going to take place.
Return Value: This method returns array of object as an output.
Exception: This method throws ParseException if the beginning of the specified string can not be parsed.
Below are the examples to illustrate the parse() 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" ;
Object[] hash = mf.parse(str);
System.out.println( "Parsed value are :" );
for ( int i = 0 ; i < hash.length; i++)
System.out.println(hash[i]);
}
catch (ParseException e) {
System.out.println( "\nString 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, date}, {2, time}, {1, number}" );
String str = "10, 20, 30" ;
Object[] hash = mf.parse(str);
System.out.println( "Parsed value are :" );
for ( int i = 0 ; i < hash.length; i++)
System.out.println(hash[i]);
}
catch (ParseException e) {
System.out.println( "String is Null" );
System.out.println( "Exception thrown : " + e);
}
}
}
|
Output:
String is Null
Exception thrown : java.text.ParseException: MessageFormat parse error!
