DecimalFormat equals() method in Java

The equals() method is a built-in method of the java.text.DecimalFormat class accepts an argument which is an object and returns true if this argument object is same as the object, else it returns false.

Syntax:

public boolean equals(Object arg)

Parameters: The function accepts a single mandatory parameter arg which specifies the object which is to be compared with.

Return Value: The function returns a boolean value. It returns true if both the objects are same else it returns false.

Below is the implementation of the above function:

Program 1:

// Java program to illustrate the
// equals() method

import java.text.DecimalFormat;
import java.util.Currency;
import java.util.Locale;

public class Main {
    public static void main(String[] args)
    {

        // Get the Currency Instance
        DecimalFormat dF1 = new DecimalFormat();
        dF1.getCurrencyInstance();

        // Get the Currency Instance
        DecimalFormat dF2 = new DecimalFormat();
        dF2.getCurrencyInstance();

        // Check if equal or not
        if (dF1.equals(dF2))
            System.out.println("Yes both are equal");
        else
            System.out.println("Yes both are not equal");
    }
}

Output:

Yes both are equal

Program 2:

// Java program to illustrate the
// equals() method

import java.text.DecimalFormat;
import java.util.Currency;
import java.util.Locale;

public class Main {
    public static void main(String[] args)
    {

        // Get the Currency Instance
        DecimalFormat dF1 = new DecimalFormat();
        dF1.getCurrencyInstance();

        // Get Instance
        DecimalFormat dF2 = new DecimalFormat();
        dF2.setCurrency(Currency.getInstance(Locale.GERMANY));

        // Check if equal or not
        if (dF1.equals(dF2))
            System.out.println("Yes both are equal");
        else
            System.out.println("Yes both are not equal");
    }
}

Output:

Yes both are not equal
