help in java program

please could you help me with my assignment I have to submit it on Monday 29 October please help me :(

Write a program to test the Person class defined below. Your test program should create
two instances of the class (each to test a different constructor) and test each of the methods. You are also required to illustrate the error in trying to access private data
members from the client class (for clarity temporarily change the private modifier to public
and test again).

class Person { // Data Members
private String name; // The name of this person private int age; // The age of this person private char gender; // The gender of this person // Default constructor public Person() { this("Not Given", 0, 'U'); } // Constructs a new Person with passed name, age, and gender. // example of explicit use of ââ?¬Å?thisââ?¬Â? (only for illustration) public Person(String name, int age, char gender) { this.age = age; this.name = name; this.gender = gender; }
// Returns the age of this person. public int getAge( ) { return age; } // Returns the gender of this person. public char getGender( ) { return gender; } // Returns the name of this person. public String getName( ) { return name; } // Sets the age of this person. public void setAge( int age ) { this.age = age; } // Sets the gender of this person. public void setGender( char gender ) { this.gender = gender; } // Sets the name of this person. public void setName( String name ) { this.name = name; } } // end class
