import java.util.ArrayList;
public class maxSec {

public static void main(String[] args) {
int maxFi=0;
int maxSe=0;
ArrayList<Integer> arl=new ArrayList<Integer>();

arl.add(4); arl.add(8); arl.add(2);
arl.add(6); arl.add(7); arl.add(8);

for(int i=0; i<arl.size(); i++){
if (maxFi< arl.get(i))
maxFi= arl.get(i);
}

for(int i=0; i<arl.size(); i++){
if (maxSe <arl.get(i)){
if (arl.get(i)<maxFi ){

maxSe=arl.get(i);
}
}
}
System.out.println(maxFi);
System.out.println(maxSe);
