heyy, i'm a student so dont attack me please i just dont understand whats wrong with this code why is it giving me an error when i make the array public? it says illegal start which doesnt make sense

package assignment;

import java.util.Scanner;


public class Assignment {

 
    public static void main(String[] args) {
        
        Scanner in= new Scanner(System.in);
        System.out.print("Enter array size! ");
        int size= in.nextInt();
        public int[] array= new int[size]; // error
        for (int i=0;i<size;i  )
        {
        System.out.println("Enter numbers: ");
        Scanner input= new Scanner(System.in);
        array[i]=input.nextInt();
        }
'''

any headsup?

Access Modifiers:

If you move the whole line outside of your main function it will work. Access Modifiers such as: "Public, Private, etc." are only allowed outside of functions/methods.

You could also remove the public tag instead of taking the variable out of the function but that would limit your scope.

Scope:

If you want to learn about scope I'd give this a go:

It's in javascript but don't let that scare you away, the concepts are the same and JS is easy.

If you want to use array outside any class or package then declare array globally with public access modifier.

import java.util.*;
public class Main
{
    public static int[] array; // declare globally
    
    public static void main(String[] args) {
        Scanner in= new Scanner(System.in);
        System.out.print("Enter array size! ");
        int size= in.nextInt();
        array = new int[size];
        for (int i=0;i<size;i  )
        {
            System.out.println("Enter numbers "   (i   1)   ": ");
            Scanner input= new Scanner(System.in);
            array[i]=input.nextInt();
        }
    }
}

Some modifier type are not allowed in method body: public, private, protect
