如何从文本文件中的 Java 中的字符串数组打印一个元素（索引）？

Question

so recently i started to picked java to learn, and i want to make a Word Per Minutes software but because i only know how to use text file as database in Java, it started to made me confuse.

so i have text.txt file, i read the.txt file into a string using scanner but i split it into words as arrays so it can appear in the label (JavaFX), lets say i want 10 words at a time, if they complete typing all 10 words, than next 10 index of words should appear as well, probably using some random() method.

but so far i did not find how to print spesific array index (each word) from a text file especially if the data it self not orginaly as arrays. i tried few method but it didnt work i know it is easier if i just type bunch of words into array in the main class, then call it later but, i wonder if i can print spesific index of word.thank you

here is my code so far

        File txt = new File("/text.txt");
        Scanner scan = new Scanner(txt);
        
        String line;
        String[] word;
        
        while (scan.hasNextLine()) {
        line= scan.nextLine();
        word= line.split(" ");
    
            for(int i=0; i<word.length; i++) {
                
                System.out.println(word[i]);
            }

I think you can do this, to find an index of a String in array.

    public static int findIndex(String[] someArray, String indexString){
    for(int i = 0; i < someArray.length; i++){
        if(someArray[i].equalsIgnoreCase(indexString))
            return i;
    }
    return -1;
}

If this method finds a String inside an array, it returns its index. If not, returns -1.
