I need a timer that only count in second with decimal part (Hundredth).some thing like this:

  thanks for the help!

1.   String[] a = split(trim(serial), ',');  //a new array (called 'a') that stores values into separate cells (separated by commas specified in  Arduino program)
2. 
   
   
3.    int s2 = int(map(int(a[1]),1,1023,1,400));
4.    int s1 = int(map(int(a[0]),1,1023,1,1023));
5. 
   
6.  for (int j = 1; j <109; j++) {
7.       if (s1==x[j]){
8.         for(int i=1; i<400 ; i++){
9.             if(s2==y[i]){     
10.      
11.                  println("Hi");
12. 
    
13.           }
14.        }
15.    }
16.  }

* x[j] and y[j] are two arrays to comparison the sensor value.

now, i have an issue,
With each iteration of the loop (every step  j <109; j++ and   i<400 ; i++ ) "Hi"  is printed.

this is my code:
what's wrong!!!!!!!!!!!!!!!

why "Hi" can not printed?

2.   String[] a = split(trim(serial), ',');  //a new array (called 'a') that stores values into separate cells (separated by commas specified in  Arduino program)
   
   
3.    float s2 = map(Integer.parseInt(a[1]),1,1023,1,400);
4.    float s1 = map(Integer.parseInt(a[0]),1,1023,1,1023);
   
   
5.  for (int j = 1; j <109; j++) {
6.       if ((s1==x[j]) &&  (second() % 5 == 0)){
7.   
8.         for(int i=1; i<400 ; i++){
9.             if((s2==y[i]) && (second() % 5 == 0)){ 
   
               println("Hi");
          }
10.      }
11.   }
12. }

-x[j] and y[j] is two arrays to comparison the sensor value.
