Hi Experts,

i want to display list values based on now(current day),last day(current date+previous day),last two days.
List<PerformanceDataValues> dataList = new ArrayList<>();
                for (Entry<String, String> entry : treemap.entrySet()) {
                    PerformanceDataValues data = new PerformanceDataValues();
                    data.setTime(entry.getKey());
                    String value = entry.getValue();
                    String computedValue = applyFormula(value, wsdlInput.getFormulae());
                    data.setValue(computedValue != null ? computedValue : value);
                    dataList.add(data);
                }

Open in new window


this list will have values as below,
every time this list will have last 3 days data.
i want to display 3 different outputs

a) days as 0
i have to display current date---> time and values information

b) days as 1
i have to display current day and previous day

c) days as 3

last 3days data

in method parameter i am passing the input value for days.
MeasurementInput input
input.getDays() will give value as 0 or 1 or  2 based on the value i have to show any of the data




dataList sample values:
=======================
 
      {
        "time": "2016-1-10 13:30:00",
        "value": 253.000
        },
        {
        "time": "2016-1-10 13:30:00",
        "value": 53.000
        },
        {
        "time": "2016-1-11 13:30:00",
        "value": 353.000
        },
        {
        "time": "2016-1-11 13:30:00",
        "value": 3.000
        },
        {
        "time": "2015-1-12 13:30:00",
        "value": 30.000
        },
        {
        "time": "2015-1-12 13:30:00",
