MessageFormat equals() method in Java with Example

The equals() method of java.text.MessageFormat class is used to check if both the MessageFormat objects are same or not.

Syntax:

public boolean equals(Object obj)

Parameter: This method takes MessageFormat objects which will be compared with the current MessageFormat object.
Return Value: if both the MessageFormat objects are equal to each other then it will return true otherwise false.
Below are the examples to illustrate the equals() method:
Example 1:

Java

// Java program to demonstrate
// equals() 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 mf1
                = new MessageFormat("{0, date, #}, {1, time, #}, {0, number}");

            // creating and initializing  MessageFormat
            MessageFormat mf2
                = new MessageFormat("{0, date, #}, {1, time, #}, {0, number}");

            // compare both object
            // using equals() method
            boolean i = mf1.equals(mf2);

            // display result
            if (i)
                System.out.println(
                    "mf1 is equals to mf2");
            else
                System.out.println(
                    "mf1 is not equal to mf2");
        }

        catch (ClassCastException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output:

mf1 is equals to mf2

Example 2:

Java

// Java program to demonstrate
// equals() 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 mf1
                = new MessageFormat("{0, date, #}, {1, time, #}, {0, number}");

            // creating and initializing  MessageFormat
            MessageFormat mf2
                = new MessageFormat("{0, date, #}, {0, time, #}, {0, number}");

            // compare both object
            // using equals() method
            boolean i = mf1.equals(mf2);

            // display result
            if (i)
                System.out.println(
                    "mf1 is equals to mf2");
            else
                System.out.println(
                    "mf1 is not equal to mf2");
        }

        catch (ClassCastException e) {

            System.out.println("Exception thrown : " + e);
        }
    }
}

Output:

mf1 is not equal to mf2
