This question has already been answered:

Why doesn't the index of the found word appear on the console?

The user enters the word. The program searches the array and displays its index:

import java.util.Scanner; public class MassiveStrings { public static void main(String[] args) { Scanner scn = new Scanner(System.in); System.out.print("Введите слово: "); String object = scn.nextLine(); String[] word = { "Масло", "Вода", "Дерево", "Кефир", "Помидор", "Сельдерей", "Кувшин" }; for (int i = 0; i < word.length; i++) { if (word[i] == object) System.out.print("Ваш индекс" + i); } } }

    To compare strings in Java, you need to use the .equals() method:

     if (word[i].equals(object))

    And word[i] == object compares the same word[i] object and object or different. Obviously different.
