this is a program where the user inputs a bunch of numbers and the program finds the nth highest number from the list, the nth number is specified by the user.



But for some reason, this program just finds the second highest number. Could anyone please help?



Here is the code:



import java.util.*;

public class nthHighest {
public static void main(String[] args) {
List<Double> numbers = new ArrayList<Double>();
Scanner input = new Scanner(System.in);
System.out.println("How many numbers do you want to input");
int howMuch = input.nextInt(); // how many numbers the user want to input
double num = 0;
for (int a = 1; a <= howMuch; a++) {
num = input.nextDouble();
numbers.add(num);//the numbers are added to the list
}
System.out.println("The nth highest number you want to find :");
int nth = input.nextInt();//the highest number user wants to find
int se;
double highest = numbers.get(0);
double nthHighest = 0;
int size = numbers.size();
se = 1;
for (int h = 1; h <= nth; h++) {
for (; se < size; se++) {
if (numbers.get(se) > highest) {
highest = numbers.get(se);
}
}
numbers.remove(highest);//removes the highest number from the list
size = numbers.size();
se = 0;
}
nthHighest = numbers.get(0);
for (int q = 0; q < numbers.size();q++){//find the nth highest number
if (numbers.get(q) > nthHighest )
nthHighest = numbers.get(q);
System.out.print(" " + numbers.get(q));
}
System.out.println();
System.out.println ("the " + nth + "th highest number is " + nthHighest);
}
}
