There is no am/pm mentioned in question, he is using hours and minutes. — CopsOnRoad, Sep 21 '18 at 11:37
@NileshRathod Exactly, she is using hours and minutes but as String. She is not using Date object which can have am/pm when fetched in proper format. — CopsOnRoad, Sep 21 '18 at 11:39
i need only hour and minute like 00:00:00 format not required Am/Pm — Darshi Patel, Sep 21 '18 at 11:39
@CopsOnRoad than she need to use this`SimpleDateFormat sdf = new SimpleDateFormat("hh:mm");` — AskNilesh, Sep 21 '18 at 11:39

1)first step remove space from string (string = "1 hour 37 minutes)

   text = string.replace(" ", "");

2) Second step replace hour to ":" and minutes by ":00"

text = text.replace("hour",":");
      text = text.replace("minutes",":00");

I guess you must code a function that format your string into what you need. Your function should be like this:

public static String formatTime(String inputTime)
{
String result = inputTime.replace(" ","");
result = result.replace("hours",":").replace("hour",":").replace("minutes","").replace("minute","");
String[] resultAux = result.split(":"); //First position will be hours, second position will be minutes

for(int i=0; i<resultAux.length; i++)
{
    if(resultAux[i].length() == 1)
    {
        resultAux[i] = "0" + resultAux[i]; //If we have 1 character in minutes we put the 0
    }
}

return String.join(":",resultAux) + ":00"; //Due to in your example you don't mention that you can have miliseconds we just put the miliseconds at the end


}

Of course you will call your function like this:

System.out.println("result is: " + formatTime("2 hours 37 minutes"));
