Exercise 5: Create a class called Dog containing two Strings: name and says. In main( ), create two dog objects with names “spot” (who says, “Ruff!”) and “scruffy” (who says, “Wurf!”). Then display their names and what they say.
Solution:
class Dog
{
String name;
String says;
void setName(String n)
{
name = n;
}
void setSays(String s)
{
says = s;
}
void showName()
{
System.out.println(name);
}
void speak()
{
System.out.println(says);
}
}
public class DogTest
{
public static void main(String[] args)
{
Dog spot = new Dog();
spot.setName("Spot");
spot.setSays("Ruff!");
Dog scruffy = new Dog();
scruffy.setName("Scruffy");
scruffy.setSays("Wurf!");
spot.showName();
spot.speak();
scruffy.showName();
scruffy.speak();
}
}
{
String name;
String says;
void setName(String n)
{
name = n;
}
void setSays(String s)
{
says = s;
}
void showName()
{
System.out.println(name);
}
void speak()
{
System.out.println(says);
}
}
public class DogTest
{
public static void main(String[] args)
{
Dog spot = new Dog();
spot.setName("Spot");
spot.setSays("Ruff!");
Dog scruffy = new Dog();
scruffy.setName("Scruffy");
scruffy.setSays("Wurf!");
spot.showName();
spot.speak();
scruffy.showName();
scruffy.speak();
}
}
Output:
