将文件值添加到数组时不兼容的字符串类型

Question

这就是我想要做的：从 .txt 文件中获取值并将它们添加到数组中。我遇到一个问题，它说：

“不兼容的类型。找到：'java.lang.String'，必需：'java.lang.String[]'”

Educate.txt 文件包含以下值： 洗脑信仰（还有更多）

这是到目前为止我的代码。扫描仪接受诸如“educate c”之类的字符串，“educate”是文件的名称。

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Scanner;

public class New {

    public static void main(String[] args) throws IOException {
        Scanner scnr = new Scanner(System.in);
        FileInputStream fileByteStream = null; //input stream
        FileOutputStream fileStream = null;
        char characterCheck;
        String textLine;
        String inputValue;
        String fileValue;
        String charValue;
        String fileName = "";
        String thirdValue;
        Scanner inFS = null; //scanner
        Scanner inSS = null;
        Scanner inKS = null;
        int NUM_CHARACTERS = 26;      // Maximum number of letters
        int MAX_WORDS = 10;           // Maximum number of synonyms per starting letter

        String[][] synonyms = new String[NUM_CHARACTERS][MAX_WORDS];  // Declare 2D array for all synonyms
        String[] words = new String[MAX_WORDS]; // The words of each input line

        inputValue = scnr.nextLine(); //accept file input
        inSS = new Scanner(inputValue);

        fileValue = inSS.next();
        charValue = inSS.next();

        if (fileValue.equals("educate")) {
            fileName = fileValue + ".txt";
        }
        else if (fileValue.equals("goal")) {
            fileName = fileValue + ".txt";
        }
        else if (fileValue.equals("happy")) {
            fileName = fileValue + ".txt";
        }
        fileByteStream = new FileInputStream("src/" + fileName); //open file
        inFS = new Scanner(fileByteStream); //assign to inFS

        while (inFS.hasNextLine()) { //loop through data line by line
            textLine = inFS.nextLine();//assign nextLine of file to variable
            inKS = new Scanner(textLine);
            for (int i = 0; i < synonyms.length; ++i) {
            synonyms[i] = inKS.next();
            }
        }
    }
}

我希望将文件中的值添加到数组中。
