示例1: main
import java.io.SequenceInputStream; //導入方法依賴的package包/類
public static void main(String[] args) throws IOException {
// SequenceInputStream(InputStream s1, InputStream s2)
// 需求：把ByteArrayStreamDemo.java和DataStreamDemo.java的內容複製到Copy.java中
InputStream s1 = new FileInputStream("ByteArrayStreamDemo.java");
InputStream s2 = new FileInputStream("DataStreamDemo.java");
SequenceInputStream sis = new SequenceInputStream(s1, s2);
BufferedOutputStream bos = new BufferedOutputStream(
new FileOutputStream("Copy.java"));
// 如何寫讀寫呢，其實很簡單，你就按照以前怎麽讀寫，現在還是怎麽讀寫
byte[] bys = new byte[1024];
int len = 0;
while ((len = sis.read(bys)) != -1) {
bos.write(bys, 0, len);
}
bos.close();
sis.close();
}
示例2: main
import java.io.SequenceInputStream; //導入方法依賴的package包/類
public static void main(String[] args) throws IOException {
// 需求：把下麵的三個文件的內容複製到Copy.java中
// ByteArrayStreamDemo.java,CopyFileDemo.java,DataStreamDemo.java
// SequenceInputStream(Enumeration e)
// 通過簡單的回顧我們知道了Enumeration是Vector中的一個方法的返回值類型。
// Enumeration<E> elements()
Vector<InputStream> v = new Vector<InputStream>();
InputStream s1 = new FileInputStream("ByteArrayStreamDemo.java");
InputStream s2 = new FileInputStream("CopyFileDemo.java");
InputStream s3 = new FileInputStream("DataStreamDemo.java");
v.add(s1);
v.add(s2);
v.add(s3);
Enumeration<InputStream> en = v.elements();
SequenceInputStream sis = new SequenceInputStream(en);
BufferedOutputStream bos = new BufferedOutputStream(
new FileOutputStream("Copy.java"));
// 如何寫讀寫呢，其實很簡單，你就按照以前怎麽讀寫，現在還是怎麽讀寫
byte[] bys = new byte[1024];
int len = 0;
while ((len = sis.read(bys)) != -1) {
bos.write(bys, 0, len);
}
bos.close();
sis.close();
