MessageFormat toPattern() method in Java with Example

The toPattern() method of java.text.MessageFormat class is used to get string representation of the current pattern of this message format object.
Syntax:

public String toPattern()

Parameter: This method does not take any argument as a parameter.
Return Value: This method returns string representation of the current pattern of this message format object.
Below are the examples to illustrate the toPattern() method:
Example 1:

Java

// Java program to demonstrate
// toPattern() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing  MessageFormat
        MessageFormat mf
            = new MessageFormat("{0, number, #}, {2, date, #.#}, {4, time}");

        // getting the pattern
        // of this MessageFormat Object
        // using toPattern() method
        String patt = mf.toPattern();

        // display the result
        System.out.println("current pattern of MessageFormat Object : " + patt);
    }
}

Output:

current pattern of MessageFormat Object : {0, number, #}, {2, date, #.#}, {4, time}

Example 2:

Java

// Java program to demonstrate
// toPattern() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing  MessageFormat
        MessageFormat mf
            = new MessageFormat("{0, number, #}, {4, time}");

        // getting the pattern
        // of this MessageFormat Object
        // using toPattern() method
        String patt = mf.toPattern();

        // display the result
        System.out.println("current pattern of MessageFormat Object : " + patt);
    }
}

Output:

current pattern of MessageFormat Object : {0, number, #}, {4, time}
