How do you construct a class in Java?

Answer 1

class User
{
// Attributes
String firstName;

// Constructor (Optional)
public User ()
{
}

// Methods

public void setFirstName(String name)
{
firstName = name;

}

public String getFirstName()
{
return firstName;

}

}

Using the class from the main method Example

public classTest
{
public static void main(String [] args)
{
// Declare User Object named u
User u;

// Set first name in object
u.setFirstName("Harvey");

// Print first name
System.out.println(u.getFirstName());

}

}
