About the error:
// You are using a no-argument constructor.
HistogramFreq freqCalc = new HistogramFreq();
...
// The HistorgamFreq class does not have a no-args
// constructor, only a one-argument constructor.
public HistogramFreq(int[] inputtedValue)
The rule is that if you do not specify a constructor for a class the vm (virtual machine) gives you one (a no-args/default constructor) for free. If you do specify a constructor with one or more arguments the vm does not provide a default no-args constructor. So if you want a no-args constructor in this case you must provide it for your class.
