Question

(Java)

how can i remove a element of a array if it contains a specific word?

—> ( ex: word= hi) , so any element that has “hi” in it will be removed.

and then recreate the array with the remaining elements?

import java.util.Scanner;

public class RemoveFromArray {
    public static void main(String[] args) {
        int size;
        Scanner scanner = new Scanner(System.in);

        // Reading size of array
        System.out.print("Enter size of array: ");
        size = scanner.nextInt();

        // Reading strings for array
        String[] array = new String[size];
        System.out.println("Enter "+size+" words for array:");
        for(int i = 0;i<size;i++){
            array[i] = scanner.next();
        }

        // Reading key to remove from array
        System.out.print("Enter word to remove: ");
        String key = scanner.next();

        // Creating new array to store strings that does not contains key
        int count = 0;
        String[] result = new String[size];

        // Storing stings that does not contan key to array result
        for(int i = 0;i<size;i++){
            if(!array[i].contains(key)){
                result[count++] = array[i];
            }
        }

        // Recreating the array
        array = new String[count];
        for(int i = 0;i<count;i++){
            array[i] = result[i];
        }

        // Printing the contents of array
        System.out.println("Content of array after removal:");
        for(int i = 0;i<count;i++){
            System.out.println(array[i]);
        }
    }
}
