Help with OOP

Question

In writing my first object and driver programs for object oriented programming I have several questions since my textbook and the java compiler seem to have different ideas of what constitutes correct code...
The errors I'm getting that I can't resolve are compile errors, I'm sure I also have many many logic errors that would prevent the program from executing correctly, but I need to address first things first.
I can't get the compiler to recognize my boolean deClawed variable in the driver program, whenever I use it I get a can't find symbol compile error (on a related note, is my boolean statement even correct? do I need to set it to something in the cat class like the rest of my variables?). I also get compile errors on my getName and getAge calls in my println statement, which is probably not the correct way to invoke that data either. This leads to my final question which is the biggest one: I don't really know what kind of approach I should be using on a program designed to collect data sets for 3 cats and respond with the name and age of each cat over 3 with claws . Should I be using a loop statement in the driver program to collect the data for each cat? Should I be using a printf statement to display the correct cat data? Am I even close with what I have? Any help would be much appreciated, even just saying what kind of statements you would use would be helpful since I can use examples and probably code them correctly and go from there.
public class HaeuserWeek6_7Cat
private String breed; //breed of cat
boolean deClawed; //T/F declawed value
private String name; //name of cat
private int age; //in years
private double weight; //in pounds
//This method sets the cat's name
public void setName(String name)
this.name = name;
     public String getName()
          return this.name;
     }//end set name
//This method sets the cat's breed
public void setBreed(String newBreed)
this.breed = breed; //age and weight are unchanged.
public String getBreed()
return this.breed;
}//end set breed
//This method sets the cat's age
public void setAge(int age)
          this.age = age;
     public int getAge()
          return this.age;
     }//end set age
//This method sets the cat's weight
     public void setWeight(double weight)
          this.weight = weight;
     public double getWeight()
          return this.weight;
     }//end set weight
//This method sets the cat's declawed T/F     
     public boolean deClawed()
          if (deClawed = true)
               return true;
          else
               return false;
     }//end isDeClawed

          System.out.println("The cats over 3 years with claws are: ");
          System.out.println("Name: " + getName);
          System.out.println("Age: " + getAge);
     else
          System.out.println("There are no cats over 3 years old with claws");
     }//end if, else
}//end main
}//end class
I've changed some of the formatting to look better on the forums so if you cut and paste into a compiler program it might add extra spaces or something.

First off, there are code tags. Use them when you post code.
The errors I'm getting that I can't resolve are compile errors, I'm sure I also have many many logic errors that would prevent the program from executing correctly, but I need to address first things first.
I can't get the compiler to recognize my boolean deClawed variable in the driver program, whenever I use it I get a can't find symbol compile error (on a related note, is my boolean statement even correct? do I need to set it to something in the cat class like the rest of my variables?).You don't try to access the deClawed member from Driver, you try to call getDeClawed(), which doesn't exist. Either change your method signature or method call to the correct name.
I also get compile errors on my getName and getAge calls in my println statement, which is probably not the correct way to invoke that data either.And those errors are? When you have questions about errors, it is always a good idea to include them verbatim in your post, otherwise we'll just invent errors and have a good laugh at your expense.
This leads to my final question which is the biggest one: I don't really know what kind of approach I should be using on a program designed to collect data sets for 3 cats and respond with the name and age of each cat over 3 with claws . Should I be using a loop statement in the driver program to collect the data for each cat? Should I be using a printf statement to display the correct cat data? Am I even close with what I have? Any help would be much appreciated, even just saying what kind of statements you would use would be helpful since I can use examples and probably code them correctly and go from there.Those are pretty vague specifications. I can think of at least 3 or 4 different ways to do that. Yes, a good design would use a loop to read in the information for each cat. For displaying the information, a set of println's is one option, and at this point probably the one you should use.
