    <p>This is the code I have writen so far in order to find the unique combinations of the integers. I recieve the number of the total integers and the length of the teams that will be created and I want to use the recursion in order to find all combinations</p> <pre><code>import java.util.ArrayList; import java.util.Collections; import java.util.Scanner; public class PartA { public static void main(String[] args) { Scanner sizeInput= new Scanner(System.in); ArrayList&lt;Integer&gt; teams= new ArrayList&lt;Integer&gt;(); int groupSize=0; int teamSize=0; System.out.println("Type the size you wish the main group to be: "); groupSize= sizeInput.nextInt(); System.out.println(" The group will be of size : "+groupSize); System.out.println("Type the size the team will have: "); teamSize= sizeInput.nextInt(); System.out.println(" The team will be of size : "+teamSize); ArrayList&lt;Integer&gt; mainGroup= new ArrayList&lt;Integer&gt;(); for(Integer i=0;i&lt;groupSize;i++){ mainGroup.add(i); int loopTimes=mainGroup.size(); int count=0; showTeams(mainGroup,teams,loopTimes,count,teamSize,groupSize); } } public static Integer showTeams(ArrayList&lt;Integer&gt;mainGroup, ArrayList&lt;Integer&gt;teams,int loopTimes,int count, int teamSize,int groupSize) { int e=0; int i=0,o; //int count=0; //int loop=U.length(); while(count&lt;=2){ for(i=0; i&lt;loopTimes-1 ; i++){ o=i+count; e=mainGroup.get(i)+mainGroup.get(o+1); System.out.println(e); } count++; loopTimes--; System.out.println(count + " " + loopTimes); if(count&gt;loopTimes) { System.out.println("Solution Found"); return e; } else { System.out.println("Recursion Call"); showTeams(mainGroup,teams,loopTimes,count,teamSize,groupSize); } } return e; } } </code></pre> <p>All I want is to print the unique combinations for the integers</p>

    1. COI think you should post the code that is not working, and the exact error you are receiving, and what you have tried already, before we can be expected to provide a reasonable answer. :)

    2. COis there a reason you need to use recursion?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
