How and why am I getting the compiler error ("class, interface, or enum expected")? Here is the code:
public class RolloverCounter{
private int counter=0;
private int max;
public RolloverCounter(int a){
if(a<0){
max = a;
}
}
public void increment()
{
for(int i=0;i<=max;i++)
{
counter++;
System.out.println(counter);
if(counter==max){
counter=0;
}
}
}
public void decrement(){
for(int i=0;i<=max;i++)
counter--;
if(counter<0)
{
counter=max;
}
System.out.println(counter);
}
public String toString() {
return counter;
}
public void reset(){
counter = 0;
}
}
}
What have I done wrong?

Your toString()
method isn't returning a String
,
public String toString() {
return counter;
}
should be something like
public String toString() {
return String.valueOf(counter);
}
Finally, you appear to have an extra closing brace (at the end) in your code as posted.
