我有一个扩展名为.ats的二进制文件，我应该将其转换为Byte数组。将文件转换为字节流后，我应该跳过一些字节。文件在WINDOWS-1255中编码。
以下代码段是否正确将其转换为字节流？
<script src="https://cdnjs.cloudflare.com/ajax/libs/jscolor/2.0.4/jscolor.js"></script>
<p>'onchange' fires after the mouse button is released
<p>Rectangle1 color:
<input class="jscolor" onchange="update(this.jscolor, 'rect1')" value="cc66ff">
<p id="rect1" style="border:1px solid gray; width:161px; height:100px;">
<p>Rectangle2 color:
<input class="jscolor" onchange="update(this.jscolor, 'rect2')" value="cc66ff">
<p id="rect2" style="border:1px solid gray; width:161px; height:100px;">
<script>
function update(jscolor, target) {
// 'jscolor' instance can be used as a string
document.getElementById(target).style.backgroundColor = '#' + jscolor
}
</script>

没有必要打开流，因为"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",

将以最有效的方式完成所有事情。
可以像这样读取任何文件的字节：
Files.readAllBytes(Path)修改
可以将数组传递给byte[] bytes = Files.readAllBytes(Paths.get(fileName));
构造函数以检索流：
ByteArrayInputStream
