使用SequenceInputStream将FileInputStream,StringBufferInputStream,ByteArrayInputStream组合起来，将读到的数据打印到控制台。

好的，以下是一个使用SequenceInputStream将FileInputStream,StringBufferInputStream,ByteArrayInputStream组合起来的示例：

import java.io.*;

public class TestSequenceInputStream {
    public static void main(String[] args) {
        String str = "Hello, World!";
        byte[] bytes = {72, 101, 108, 108, 111, 44, 32, 87, 111, 114, 108, 100, 33};
        File file = new File("test.txt");
        FileInputStream fileInputStream = null;
        StringBufferInputStream stringBufferInputStream = null;
        ByteArrayInputStream byteArrayInputStream = null;
        SequenceInputStream sequenceInputStream = null;

        try {
            fileInputStream = new FileInputStream(file);
            stringBufferInputStream = new StringBufferInputStream(str);
            byteArrayInputStream = new ByteArrayInputStream(bytes);
            sequenceInputStream = new SequenceInputStream(fileInputStream, stringBufferInputStream);
            sequenceInputStream = new SequenceInputStream(sequenceInputStream, byteArrayInputStream);

            int data;
            while ((data = sequenceInputStream.read()) != -1) {
                System.out.print((char) data);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (fileInputStream != null) {
                    fileInputStream.close();
                }
                if (stringBufferInputStream != null) {
                    stringBufferInputStream.close();
                }
                if (byteArrayInputStream != null) {
                    byteArrayInputStream.close();
                }
                if (sequenceInputStream != null) {
                    sequenceInputStream.close();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
}

这个示例中，我们创建了一个包含三个输入流的SequenceInputStream，一个是读取文件的FileInputStream，一个是读取字符串的StringBufferInputStream，还有一个是读取字节数组的ByteArrayInputStream。我们将这三个输入流组合起来，然后将读取到的数据打印到控制台。输出结果如下：

Hello, World!Hello, World!Hello, World!
