The parse() method of java.text.MessageFormat class is used to parse the string object starting from the passed parse position in the parse() method.
Syntax:
public Object[] parse(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 parse() method:
Example 1:
Java
// Java program to demonstrate// parse() methodimport 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(3); // parsing the string starting from pos // according to MessageFormat // using parse() method Object[] hash = mf.parse(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("\nParse position is Null"); System.out.println("Exception thrown : " + e); } }} |
Output:
Parsed value are : 456 30.444 20.325
Example 2:
Java
// Java program to demonstrate// parse() methodimport 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(3); // parsing the string starting from pos // according to MessageFormat // using parse() method Object[] hash = mf.parse(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); } }} |
Output:
Parse position is Null Exception thrown : java.lang.NullPointerException
