Question

I write the following two functions
I want to implement the functions with HashMap ( in place of functions )
how to do that?

static void someFunction(int count, int[] anArray)  
{      
  for ( int i=0;i<anArray[count];i = i + 1) 
  {
    System.out.print("#");
  }
  System.out.println("");
} 

static void someFunctionB(int[] anArray , int count,  String stringfinal, String sttr)  
{      
  anArray[count]= stringfinal.replaceAll("[^"+sttr+"]", "").length();
}   

someFunctionB(anArray ,  count,   stringfinal,  sttr  );        

someFunction(count, anArray);  

Answer 1

Without using any functions (apart from public static void main(String[] args)), you could do something like:

Map<Integer, Integer> mapThatPretendsToBeAnArray = new LinkedHashMap<Integer, Integer>();
mapThatPretendsToBeAnArray.put(0, 17);
mapThatPretendsToBeAnArray.put(1, 5);
mapThatPretendsToBeAnArray.put(2, 1);
mapThatPretendsToBeAnArray.put(3, 319);

//someFunction()
for (int i = 0; i < mapThatPretendsToBeAnArray.get(1); i++) {
    System.out.print("#");
}
System.out.println("");

//someFunctionB()
mapThatPretendsToBeAnArray.put(3, "stringFinal".replaceAll("[^"+"sttr"+"]", "").length());

But of course, someFunction() and someFunctionB() are more useful, because they let you parameterize your arguments instead of having to pick hard-coded ones as in this example.
