Lab 4 deals with private member variables, and javadoc.
Private Member Variables
- Login to beowulf2.csc.smith.edu, grendel.csc.smith.edu, or use one of the Linux Mint machines.
- Create a new program called Animal1.java containing the code below:
public class Animal {
boolean isVaccinated;
boolean isTattooed;
String name;
int age;
Animal( String n, int a, boolean v, boolean t ) {
name = n;
age = a;
isVaccinated = v;
isTattooed = t;
}
public void displayBasicInfo( ) {
String v = "vaccinated";
if ( !isVaccinated ) v = "not " + v;
String t = "tattooed";
if ( !isTattooed ) t = "not " + t;
System.out.println( String.format( "%s (%d), %s, %s",
name, age, t, v ) );
}
public static void main(String[] args) {
Animal a = new Animal( "Max", 3, false, true );
a.displayBasicInfo();
a.v = true;
a.age = 5;
a.displayBasicInfo();
}
}
