import java.util.*;
import java.io.*;

public class ShufflingListAndArray{
public static void main(String[] args) throws IOException{
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.print("How many elements you want to add to the list: ");
int n = Integer.parseInt(in.readLine());
System.out.print("Enter " + n + " numbers to sort: ");
List<Integer> list = new ArrayList<Integer>();
for(int i = 0; i < n; i++){
list.add(Integer.parseInt(in.readLine()));
}
Collections.shuffle(list);
Collections.sort(list);
System.out.println("List sorting :"+ list);
}
}

Hi,
line-> list.add(Integer.getInteger(in.readLine())); here List object has declare to hold Interger type using java generics. But Interger.parseInt(String) returns java primitive int.so it gives datatype compatibility while compiling. ofcourse this is small logical bugs.

Thanks,
