A list of all binary combinations of numbers in Java

I'm working on a project involving "dynamic programming". I'm shocked by this trivial thing. Please help

Suppose I take 4 as input, I want to display something similar to: 0000 to 1111

However, if I enter 5, I want to display as follows: 00000 to 11111, and so on

Thank you in advance,

Editor: please don't post the code It's not a homework problem. I don't need any code. Just tell me its logic and I'll be happy

Edit2: stackoverflow is happening in wth. I asked if you have written code for me? I hope the man who voted for it What's the point of this forum if I can't help?

Share logic with me We can talk about it. I don't need this code

Editor 3: I publish the code I tried here I hope this "satisfaction" to everyone who thinks I haven't tried

import java.util.ArrayList;

Public class regularinvestigator{

public ArrayList createCombinations(ArrayList listOfFlightNumbers){

ArrayList<String> result = new ArrayList<String>();

for(int i = 1; i < listOfFlightNumbers.size(); i++) {

  String binaryEqvivalent = Integer.toBinaryString(i);System.out.println(binaryEqvivalent);
  String element = "";

  for(int j = 0; j < binaryEqvivalent.length(); j++)
    if(binaryEqvivalent.charAt(j) == '1')
      element += listOfFlightNumbers + " ";

  result.add(element.substring(0,element.length() - 1));
}

return result;

}

private String getContent(ArrayList<String> flight) {
String temp = "";

for(int i = 0; i < flight.size() - 1; i++)  temp += flight.get(i) + " ";

temp += flight.get(flight.size() - 1);

return temp;

}

private ArrayList removeElementAtIndex(ArrayList flight,int position){

ArrayList<String> res = new ArrayList<String>();

for(int i = 0; i < flight.size(); i++) {
  if(i != position) res.add(flight.get(i));
}

return res;

} }

Editor 4: Thank phoxis, pengone, Jerry coffin and oliholz for their valuable answers:)

Solution

>Get input > from I = 0 to (2 ^ n) – 1 count > for each value of the I-bit mask, each bit I and is displayed
