如何将ojalgo稀疏数组存储到java文件中？

import org.ojalgo.array.Array1D;
import org.ojalgo.array.BasicArray;
import org.ojalgo.array.Primitive64Array;

int size = 100; // 数组大小
int nonZeros = 10; // 非零元素个数

BasicArray<Double> array = Primitive64Array.makeSparse(size, nonZeros);

int index = 5; // 元素索引
double value = 10.0; // 元素值

array.set(index, value);

String filePath = "path/to/your/file.java"; // 文件路径

try (BufferedWriter writer = new BufferedWriter(new FileWriter(filePath))) {
    writer.write("double[] sparseArray = new double[" + size + "];");
    writer.newLine();

    for (int i = 0; i < size; i++) {
        double element = array.get(i);
        if (element != 0.0) {
            writer.write("sparseArray[" + i + "] = " + element + ";");
            writer.newLine();
        }
    }
} catch (IOException e) {
    e.printStackTrace();
}
