package ArrayList;

What is the difference between clear () ; and removeAll(); ?

[linkonahad]

package basicjava;

import java.util.Scanner;
import java.util.ArrayList;
public class ArrayList2 {
public static void main(String[] args) {
Scanner input = new Scanner (System.in);
ArrayList<Integer>a = new ArrayList <Integer> ();
System.out.print("Enter how many number you want : ");
int n=input.nextInt(), x;
System.out.print("Enter the values : ");
for (int i = 0; i < n; i++) {
x=input.nextInt();
a.add(i, x);
}
System.out.println(a);
}
}
Sir, is this method is effective?
