I have no idea about Java...
See the comments in the code marked with 'HERE X.) <<<<< '

import java.util.ArrayList;

public class ArrayListDemo {

    public static void main(String[] args) 
        {
            // HERE A.)  <<<<<<<<<<<< 
            //List<Integer> arrayList = new ArrayList<Integer>();
            ArrayList<Integer> arrayList = new ArrayList<Integer>();

            for (int i = 1; i<5 ; i++)
                arrayList.add(i);
        // HERE B.)  <<<<<<<<<<<<  
        //}

        //Printing elememts
        System.out.println(arrayList);

        //Remove element at index 3
        arrayList.remove(3);

        //Displaying the ArrayList
        //after deletion 
        System.out.println(arrayList);

        //printing elememts one by one 
        for (int i = 0; i<arrayList.size(); i++) {
            System.out.print(arrayList.get(i)+ " ");
        }

    // HERE C.)   <<<<<<<<<<<<  
    }
}

The positions of '{' and '}' matters. And a correct indentation highlight related problems.

Advice: Learn to indent properly your code, it show its structure and it helps reading and understanding. It also helps spotting structures mistakes.

Java

import java.util.ArrayList;

public class ArrayListDemo {

  public static void main(String[] args) {
    List < Integer > arrayList = new ArrayList < Integer > ();

    for (int i = 1; i < 5; i++)
      arrayList.add(i);
  }

  //Printing elememts
  System.out.println(arrayList);

  //Remove element at index 3
  arrayList.remove(3);

  //Displaying the ArrayList
  //after deletion 
  System.out.println(arrayList);

  //printing elememts one by one 
  for (int i = 0; i < arrayList.size(); i++) {
    System.out.print(arrayList.get(i) + " ");
  }

}
