如何将矩阵的不同行传递给threadPool。[ JAVA ]

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class MatrixThreadPoolExample {
    public static void main(String[] args) {
        int[][] matrix = {
                {1, 2, 3},
                {4, 5, 6},
                {7, 8, 9}
        };

        int rows = matrix.length;
        int cols = matrix[0].length;

        ExecutorService threadPool = Executors.newFixedThreadPool(rows);

        for (int i = 0; i < rows; i++) {
            final int row = i;
            threadPool.execute(() -> processRow(matrix, row, cols));
        }

        threadPool.shutdown();
    }

    private static void processRow(int[][] matrix, int row, int cols) {
        for (int j = 0; j < cols; j++) {
            System.out.println("Processing element at row " + row + ", column " + j + ": " + matrix[row][j]);
            // 在这里可以进行具体的矩阵行处理操作
        }
    }
}
