Algorithms:counter Counter Detailed

Counter counter, in the algorithm, has a very important application, including a name (name-string), a counter (count-int);

can increment (increment), return count value (tally), can print by default (toString);

The code is as follows:

public class Counter   
{  
    private final String name;  
    private int count;  
          
    Public Counter (String ID) {  
        name = ID;  
    }  
          
    public void Increment () {  
        count++;  
    }  
      
    public int tally () {return  
        count;  
    }  
          
    Public String toString () {return  
        count + "" + Name;  
    }  
          
    public static void Main (string[] args) {  
        Counter heads = new Counter ("heads");  
        Counter tails = new Counter ("Tails");  
              
        Heads.increment ();  
        Heads.increment ();  
        Tails.increment ();  
              
        STDOUT.PRINTLN (heads + "" + tails);  
        Stdout.println (heads.tally () + tails.tally ());  
    }  

Output:

2 heads 1 Tails  
3
