本文整理了Java中java.io.ByteArrayOutputStream.<init>()方法的一些代码示例，展示了ByteArrayOutputStream.<init>()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ByteArrayOutputStream.<init>()方法的具体详情如下：
包路径：java.io.ByteArrayOutputStream
类名称：ByteArrayOutputStream
方法名：<init>

ByteArrayOutputStream.<init>介绍

[英]Constructs a new ByteArrayOutputStream with a default size of 32 bytes. If more than 32 bytes are written to this instance, the underlying byte array will expand.
[中]构造默认大小为32字节的新ByteArrayOutputStream。如果写入此实例的字节数超过32个，则基础字节数组将展开。

代码示例

ByteArrayOutputStream result = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int length;
while ((length = inputStream.read(buffer)) != -1) {
  result.write(buffer, 0, length);
}
return result.toString("UTF-8");

    // Should never happen.
    throw new IllegalArgumentException("Failed to store [" + source + "] into String", ex);
