NumberFormat equals() method in Java with Examples

The equals() method is a built-in method of the java.text.NumberFormat 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 implement
// the above function
import java.text.NumberFormat;

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

        // Get the Currency Instance
        NumberFormat nF1
            = NumberFormat
                  .getCurrencyInstance();

        // Get the Currency Instance
        NumberFormat nF2
            = NumberFormat
                  .getCurrencyInstance();

        // Check if equal or not
        if (nF1.equals(nF2))
            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 implement
// the above function
import java.text.NumberFormat;

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

        // Get the Currency Instance
        NumberFormat nF1
            = NumberFormat
                  .getCurrencyInstance();

        // Get the Instance
        NumberFormat nF2
            = NumberFormat
                  .getInstance();

        // Check if equal or not
        if (nF1.equals(nF2))
            System.out.println("Yes both are equal");
        else
            System.out.println("both are not equal");
    }
}

Output:

both are not equal
