The equals() method of java.text.DecimalFormatSymbols class in Java is used to check for equality of this DecimalFormatSymbols with the specified DecimalFormatSymbols. This method takes a DecimalFormatSymbols instance and compares it with this DecimalFormatSymbols and returns a boolean value representing the same.

Syntax:

public boolean equals(Object obj)

Parameter: This method accepts a parameter obj which is the DecimalFormatSymbols to be checked for equality with this DecimalFormatSymbols.

Return Value: This method returns an boolean which tells if this DecimalFormatSymbols is equal to the specified Object.

Exception: This method do not throw any Exception.

Program:

// Java program to demonstrate
// the above method

import java.text.*;
import java.util.*;

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

        DecimalFormatSymbols dfs1
            = new DecimalFormatSymbols();

        System.out.println("DecimalFormatSymbols 1: "
                           + dfs1);

        DecimalFormatSymbols dfs2
            = new DecimalFormatSymbols(
                new Locale("JAPANESE"));

        System.out.println("DecimalFormatSymbols 2: "
                           + dfs2);

        DecimalFormatSymbols dfs3
            = (DecimalFormatSymbols)dfs1.clone();

        System.out.println("DecimalFormatSymbols 3: "
                           + dfs3);

        System.out.println("Comparing DFS 1 and DFS 2: "
                           + dfs1.equals(dfs2));

        System.out.println("Comparing DFS 2 and DFS 3: "
                           + dfs2.equals(dfs3));

        System.out.println("Comparing DFS 1 and DFS 3: "
                           + dfs1.equals(dfs3));
    }
}

Output:

DecimalFormatSymbols 1: java.text.DecimalFormatSymbols@1073a
DecimalFormatSymbols 2: java.text.DecimalFormatSymbols@1073a
DecimalFormatSymbols 3: java.text.DecimalFormatSymbols@1073a
Comparing DFS 1 and DFS 2: false
Comparing DFS 2 and DFS 3: false
Comparing DFS 1 and DFS 3: true
