What is a char * array?

Character Array in Java is an Array that holds character data types values. In Java programming, unlike C, a character array is different from a string array, and neither a string nor a character array can be terminated by the NUL character.

How do you declare a char array?

Declaration of a char array is similar to the declaration of a regular array in java. “char[] array_name” or “char array_name[]” are the syntaxes to be followed for declaration. After declaration, the next thing we need to do is initialization. “array_name = new char[array_length]” is the syntax to be followed.
