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
