I am developing an Math quiz app.In that it consist of 9 levels ,each level consist of 10 questions which generates random operands from array.In particular level,it generates random operands ,I have to pass these operands to another level.For example:if level 1 1st input is randomly 4 and 3 ,the level 2 1st input should be 3 and 4 likewise it should pass all 10 set operands to another level .I have share code with this,please help me out it.
public class levelFour extends AppCompatActivity implements View.OnClickListener {
int qid = 0,score=0;
private int answer=0,operand1=0,operand2=0;

This is one level which generates random values for 10 questions ,I want to use the same order of question which is generated randomly in another level. For EX: Level 1 input 1: 4 and 3 input 2: 2 and 3 (generates randomly) Level 2 input 1: 3 and 4 input 2: 3 and 2 (from level 1 input)
