如何在java中读取文件并将特定的浮点值设置为特定的数组？

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public static double[] readAndSetFloatValues(String filePath, double specificValue) {
    double[] floatArray = null;
    try {
        BufferedReader reader = new BufferedReader(new FileReader(filePath));
        String line;
        int count = 0;
        while ((line = reader.readLine()) != null) {
            double floatValue = Double.parseDouble(line);
            if (floatValue == specificValue) {
                if (floatArray == null) {
                    floatArray = new double[1];
                    floatArray[0] = floatValue;
                } else {
                    double[] tempArray = new double[floatArray.length + 1];
                    System.arraycopy(floatArray, 0, tempArray, 0, floatArray.length);
                    tempArray[floatArray.length] = floatValue;
                    floatArray = tempArray;
                }
                count++;
            }
        }
        reader.close();
        System.out.println("Found " + count + " occurrences of the specific value.");
    } catch (IOException e) {
        e.printStackTrace();
    }
    return floatArray;
}

String filePath = "path/to/your/file.txt";
double specificValue = 3.14; // 设置特定的浮点值
double[] result = readAndSetFloatValues(filePath, specificValue);
