对象类实现 Serializable 接口: 使你的对象类实现 Serializable 接口,以便它能够被序列化。 将对象序列化为 byte[]: 使用 ObjectOutputStream 将对象写入 ByteArrayOutputStream,从而获得字节数组。 将byte[] 反序列化为对象: 使用 ObjectInputStream 从ByteArrayInputStream 中读取字节数据并将其转换回对象。
步骤2:使用ObjectOutputStream 接下来,我们需要创建一个ObjectOutputStream实例,用于将对象写入字节数组中。 importjava.io.ByteArrayOutputStream;importjava.io.IOException;importjava.io.ObjectOutputStream;publicclassObjectToByteArray{publicstaticvoidmain(String[]args){Personperson=newPerson("John",30);// 创建一...
1、字节数组 字节 节点流 输入流 ByteArrayInputStream read(byte[] b, int off, int len)+close() 输出流 ByteArrayOutputStream write(byte[] b, int off, int len)+ toByteArray() 这是个新增方法,不要使用多态 package IOOthers; import java.io.BufferedInputStream; import java.io.ByteArrayInputS...
ByteArrayInputStream是InputStream的一个具体实现类,用于从字节数组中读取数据。 下面是一个示例代码: 代码语言:txt 复制 import java.io.ByteArrayInputStream; import java.util.List; import java.util.stream.Collectors; import java.util.stream.Stream; public class StreamToInputStreamExample { public static...

private static void saveDataToFile(String fileName) { try (ObjectOutputStream outputStream = new ObjectOutputStream(new FileOutputStream(fileName))) { // 将对象保存到文件 MyObject obj = new MyObject("Hello, ObjectInputStream!"); outputStream.writeObject(obj); ...
writeObject(data); // 从流里读出来 ByteArrayInputStream bi = new ByteArrayInputStream(bo.toByteArray()); ObjectInputStream oi = new ObjectInputStream(bi); @SuppressWarnings("unchecked") T data1 = (T) oi.readObject(); this.data = data1; } catch (ClassNotFoundException e) { // TODO...

Now, the objStream can be used to read objects from the file. Methods of ObjectInputStream The ObjectInputStream class provides implementations of different methods present in the InputStream class. read() Method read() - reads a byte of data from the input stream readBoolean() - reads data...
