java - java调用递归方法

Question

我定义了一个递归方法(至少我相信它是递归的)，它返回 void 并想在另一个方法中调用它，但不知道如何调用。我知道这是非常基本的，但是有人可以帮忙吗？谢谢。

递归方法:

private static void recursiveWhiteToBlack(BufferedImage image, int width, int height){
    image.getRaster().setPixel(width,height, new int [] {0, 0, 0, 0, 0, 0});        
    int[][] neighbors = neighborsXY(width,height);

    for(int i = 0; i<neighbors.length; i++){
        int neighborX = neighbors[i][0];
        int neighborY = neighbors[i][1];
        int[] neighborColor = image.getRaster().getPixel(neighborX, neighborY, new int[] {0, 0, 0, 0, 0, 0});

        if(neighborColor[0] == 1){
            recursiveWhiteToBlack(image, neighborX, neighborY);
        }   
    }   
}

调用它:

public static BufferedImage countObjects(BufferedImage image, BufferedImage original, ComponentPanel panel){
      BufferedImage target = copyImage(image);

      for(int width=1; width<image.getRaster().getWidth()-1; width++){ //Determine the dimensions for the width (x)         

          for(int height=1; height<image.getRaster().getHeight()-1; height++){ //Determine the dimensions for the height (y)

              int[] pixel = image.getRaster().getPixel(width, height, new int[] {0, 0, 0, 0, 0, 0});

              if(pixel[0] == 1){                      
                   none = recursiveWhitetoBlack(image, width, height);  //HOW TO CALL IT HERE!!!//

              }

      System.out.println("countObjects method called");
        return target;

    }

你可以这样调用它:

if(pixel[0] == 1){                      
     recursiveWhitetoBlack(image, width, height);
}

由于该方法没有返回类型，因此不需要变量赋值。
