Charset equals() method in Java with Examples

The contains() method is a built-in method of the java.nio.charset checks if a given object of charset is equal to another given object of the charset. Two charsets are considered equal if, and only if, they have the same canonical names. A charset is never equal to any other type of object.

Syntax:

public final boolean equals(Object other)

Parameters: The function accepts a single mandatory parameter other which specifies the reference object with which it is compared with.



Return Value: The function returns a boolean value. It returns true if it is equal, else it returns false.

Below is the implementation of the above function:
