mejora de funcion.

Excuse me for my english level, I know could be better

The first

if(bole==false)

have no sense because in this point bole ALWAYS will be false.

bol will be 0 if it's not a number, 1 if it's a integer and 3 if it's a double, is this what you want?

A better way to do the same with less code line is:

Código JAVA:

System.out.println(testNum("10.50")); 
........ 
   public static int testNum(String numero) { 
      int bol=0;  
       int number ; 
       double num ; 
       try { 
            Integer.parseInt(numero); 
            bol=1; 
       }        
       catch (NumberFormatException e) { 
          try { 
            Double.parseDouble(numero); 
            bol=3; 
          } 
          catch(NumberFormatException e) { 
                e.printStackTrace();    
          } 
       } 
       finally { 
        return bol; 
          } 
       } 
   }
