DecimalFormatSymbols equals() method in Java with Examples

The equals() method in the DecimalFormatSymbols class of Java is used to compare two DecimalFormatSymbols objects for equality. It returns true if the two objects are equal, i.e., if they have the same set of symbols for decimal separator, grouping separator, percent sign, and so on.

Syntax:

public boolean equals(Object obj)

Parameters: - obj: the object to compare with the current object.

Returns: - true if the two objects are equal, false otherwise.

Example 1:

DecimalFormatSymbols dfs1 = new DecimalFormatSymbols(Locale.US);
DecimalFormatSymbols dfs2 = new DecimalFormatSymbols(Locale.US);
boolean result = dfs1.equals(dfs2);
System.out.println(result); // Output: true

In this example, we create two DecimalFormatSymbols objects with the same locale (US) and compare them using the equals() method. Since they have the same set of symbols, the method returns true.

Example 2:

DecimalFormatSymbols dfs1 = new DecimalFormatSymbols(Locale.US);
DecimalFormatSymbols dfs2 = new DecimalFormatSymbols(Locale.FRANCE);
boolean result = dfs1.equals(dfs2);
System.out.println(result); // Output: false

In this example, we create two DecimalFormatSymbols objects with different locales (US and France) and compare them using the equals() method. Since they have different sets of symbols, the method returns false.

Note: The equals() method is inherited from the Object class, so it compares the objects based on their memory addresses by default. However, the DecimalFormatSymbols class overrides this method to compare the objects based on their symbol sets.
