Code standard for get/set or static int?

Question

What is the standard for getting setting values in a class?
ie.
static int VALUE = 0;
String[] values = new String[1];
public void set(int in, String val){
     values[in] = val;
public String get(int in){
     return values[in];
}OR
String val1;
String val2;
public String getVal1(){
     return val1;
public void setVal1(String in){
     val1 = in;

Answer 1

I would say the first is Very Bad, and the second is Good. In-between is Bad, which would be storing everything in a Map, where at least the values are named rather than having an anonymous number to identify them.
With that said, where I work we actually have a class that uses the Bad solution that I outlined, but it's designed to be exposed publicly by subclasses using the standard getter/setter idiom, and the map itself is not used externally. So instead of being backed by variables, all the getters and setters are backed by a Map. It ends up being Not So Bad. :-)
