# HackerRank Java List problem solution

In this HackerRank java List problem in the java programming language you have Given a list, L, of N integers, perform Q queries on the list. Once all queries are completed, print the modified list as a single line of space-separated integers.

## HackerRank Java List problem solution.

```import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;

public class Solution {

public static void main(String[] args) {
final Scanner in = new Scanner(System.in);
final int size = in.nextInt();
final List<Integer> list = new LinkedList<>();
for (int i = 0; i < size; i++) {
}
final int commandCount = in.nextInt();
for (int i = 0; i < commandCount; i++) {
in.nextLine();
String command = in.nextLine();
//            System.out.println("command: " + command);
if (command.equals("Insert")) {
int index = in.nextInt();
//                System.out.println("index: " + index);
int value = in.nextInt();
//                System.out.println("value: " + value);
} else {
int index = in.nextInt();
list.remove(index);
}
}
int count = 0;
for (Integer number : list) {
System.out.print(number);
if (count != list.size() - 1) {
System.out.print(" ");
}
count++;
}
}
}```

## Second solution

```import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;

public class Solution {

public static void main(String[] args) {
/* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
while (n-- > 0) {
int v = sc.nextInt();
}
int m = sc.nextInt();
while (m-- > 0) {
String s = sc.next();
if (s.equals("Insert")) {
int a = sc.nextInt();
int b = sc.nextInt();
} else {
int x = sc.nextInt();
list.remove(x);
}
}
for (Integer i : list) {
System.out.print(i+" ");
}

}
}```

### The solution in java8 programming

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

public class Solution {

public static void main(String[] args) {
/* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */
Scanner sc = new Scanner(System.in);
int N = sc.nextInt();
List L = new ArrayList();
for(int i = 0; i < N; i++)
int Q = sc.nextInt();
sc.nextLine();
for(int i = 0; i < Q; i++) {
String s1 = sc.nextLine();
String s2 = sc.nextLine();
if(s1.equalsIgnoreCase("Insert")){
String arr[] = s2.split(" ");
int x = Integer.parseInt(arr[0]);
int y = Integer.parseInt(arr[1]);
}
if(s1.equalsIgnoreCase("Delete")){
int x = Integer.parseInt(s2);
L.remove(x);
}
}
Iterator itr = L.iterator();
while(itr.hasNext()){
int x = (int)itr.next();
System.out.print(x + " ");
}
sc.close();
}
}```
