How to check and match the possible combinations of arraylist elements
- by Jessy
String [] A = {"High","Medium","Low"};
String [] B = {"High","Medium","Low"};
String [] C = {"High","Medium","Low"};
String [] D = {"High","Medium","Low"};
String [] E = {"High","Medium","Low"};
String [] F = {"High","Medium","Low"};
JComboBox Ai = new JComboBox(A); JComboBox Bi = new JComboBox(B);
JComboBox Ci = new JComboBox(C); JComboBox Di = new JComboBox(C);
JComboBox Ei = new JComboBox(E); JComboBox Fi = new JComboBox(F);
....
//add the user choice in arrayList
ArrayList<String> a = new ArrayList<String>();
a.add((String) Ai.getSelectedItem());
a.add((String) Bi.getSelectedItem());
a.add((String) Ci.getSelectedItem());
a.add((String) Di.getSelectedItem());
a.add((String) Ei.getSelectedItem());
a.add((String) Fi.getSelectedItem());
Scenario:
On each comboBox, user need to choose one, which mean there are 6 choices at the end.
There are 6*5*4*3*2*1 = 720 possible combinations of choices made by the user.
What is the best way to check and match the user choice without writing the 720 else if ?
e.g.
if(Ai=="High" && Bi=="High" && Ci=="Low" && Di=="High" && Ei=="Low" && Fi=="Medium") {
System.out.println("Good Choice");
}
Thank you.
