ChoiceFormat equals() method in Java with Examples

The java.text.ChoiceFormat is a class containing an equals() as a function. When two ChoiceFormat objects are compared, the ChoiceFormat class is utilized to determine the Boolean value of the comparison.

Syntax:

Parameter:

-where Obj is a parameter, an entirely distinct ChoiceFormat object for comparison, that this function accepts.

Return Value:

If both choice format objects have the same value, this function returns true; otherwise, it returns false.

Example 1:

The equals() function of the ChoiceFormat class is used in the provided Java application as an example.

Implementation:

FileName: ChoiceFormatEqualsExample1.java

import java.text.*;
import java.util.*;
import java.io.*;
public class ChoiceFormatEqualsExample1 
{
	public static void main(String[] argv)
	{
		// initialize and create the first ChoiceFormat
		ChoiceFormat cf1 = new ChoiceFormat( "Hello | Welcome | to | World");
		// initialize and create the second ChoiceFormat
		ChoiceFormat cf2 = new ChoiceFormat( "Hello | Welcome | to | World");
		// comparing cf1 and cf2 with 
		// the equals() function
		boolean if_equal = cf1.equals(cf2);
		if (if_equal)
		{
		    System.out.println("The two ChoiceFormat objects are equal.");   
		}
		else
		{
		    System.out.println("The two ChoiceFormat objects are not equal.");
		}
	}
}

Output:

The two ChoiceFormat objects are equal.

Example 2:

The Java program that is provided demonstrates how to transform numerical ranges to matching string formats using the ChoiceFormat class.

Implementation:

FileName: ChoiceFormatExample2.java

import java.text.*;
import java.io.*;
import java.util.*;
public class ChoiceFormatExample2 
{
    public static void main(String[] args) 
    {
        // Specify ranges along with associated formats.
        double[] limit = {1, 2, 3, 4, 5};
        String[] format = {"ONE", "TWO", "THREE", "FOUR", "FIVE"};
        // initialize and create a ChoiceFormat object
        ChoiceFormat ch_for1 = new ChoiceFormat(limit, format);
        // initialize and create another ChoiceFormat object with the 
        // same limits and formats
        ChoiceFormat ch_for2 = new ChoiceFormat(limit, format);
        // Examine the two ChoiceFormat objects in comparison.
        if (ch_for1.equals(ch_for2)) {
            System.out.println("The two ChoiceFormat objects are equal.");
        } else {
            System.out.println("The two ChoiceFormat objects are not equal.");
        }
    }
}

Output:
