inputStream扩展InputStream的新类(inputStream new class that extends InputStream)

 我创建了一个扩展InputStream的新类，并且必须使用@Override read（）。 我试图使用方法read（int b），但是当我使用它时，它转到方法read（），我不能使用参数，我转过来。 
 
 这是我的代码： 
 
public class Run {

    public static void main(String[] args) {

        DFSMaze3dGenerator mg = new DFSMaze3dGenerator();
        try {
            Maze3d maze3d = mg.generate(1, 5, 5);
            maze3d.print3DMaze();
            OutputStream out = new MyCompressorOutputStream(
                    new FileOutputStream("1.maz"));
            out.write(maze3d.toByteArray());
            byte[] arr = maze3d.toByteArray();
            System.out.println("");
            for (int i = 0; i < arr.length; i++) {
                System.out.print(arr[i] + ",");
            }
            out.close();
            InputStream in = new MyDecompressorInputStream(new FileInputStream(
                    "1.maz"));
            byte b[] = new byte[maze3d.toByteArray().length];
            in.read(b);
            in.close();
            Maze3d loaded = new Maze3d(b);
            System.out.println(loaded.equals(maze3d));

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}
 
 我在使用该方法时如何使用该参数：read（b）; ??? 
 
public class MyDecompressorInputStream extends InputStream {

    InputStream in;
    int count;
    boolean even = false;

    public MyDecompressorInputStream(InputStream in) {
        super();
        this.in = in;
    }

    @Override
    public int read() throws IOException {

        return 100;

    }



}

I made a new class that extends InputStream and has to @Override read(). I am trying to use the method read(int b), but when I use it,it goes to the method read() and I cant use the parameter,I passed over.
 
Here is my code:
 
public class Run {

    public static void main(String[] args) {

        DFSMaze3dGenerator mg = new DFSMaze3dGenerator();
        try {
            Maze3d maze3d = mg.generate(1, 5, 5);
            maze3d.print3DMaze();
            OutputStream out = new MyCompressorOutputStream(
                    new FileOutputStream("1.maz"));
            out.write(maze3d.toByteArray());
            byte[] arr = maze3d.toByteArray();
            System.out.println("");
            for (int i = 0; i < arr.length; i++) {
                System.out.print(arr[i] + ",");
            }
            out.close();
            InputStream in = new MyDecompressorInputStream(new FileInputStream(
                    "1.maz"));
            byte b[] = new byte[maze3d.toByteArray().length];
            in.read(b);
            in.close();
            Maze3d loaded = new Maze3d(b);
            System.out.println(loaded.equals(maze3d));

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}
 
How can i use the parameter when i use the method: read(b); ???
 
public class MyDecompressorInputStream extends InputStream {

    InputStream in;
    int count;
    boolean even = false;

    public MyDecompressorInputStream(InputStream in) {
        super();
        this.in = in;
    }

    @Override
    public int read() throws IOException {

        return 100;

    }



}
