How can I display a byte array as a String in java's debug detail formatter?
提问by Chris R
I'd like to write a simple detail formatter that displays byte[]data in the form of a String(using String.<init>([B)to do the dirty work).
我想编写一个简单的细节格式化程序，byte[]以 a 的形式显示数据String（String.<init>([B)用于做脏活）。
However, I'm not sure how to find the class name for [Bto use when creating the formatter. Is this even possible? Or, alternatively, is there another way to view byte arrays as strings in the debugger?
但是，我不确定如何找到[B在创建格式化程序时使用的类名。这甚至可能吗？或者，是否有另一种方法可以在调试器中将字节数组视为字符串？

I don't know how to get eclipse's detail formatter to automagically display byte arrays as Strings, but you can display a particular byte array by adding new String(byteArray)as a watch expression.
我不知道如何让 eclipse 的详细信息格式化程序自动将字节数组显示为字符串，但是您可以通过添加new String(byteArray)为监视表达式来显示特定的字节数组。

If your question is how would I get a string representation of a byte array of [0,1,2] to be "[0,1,2]", I would suggest you take a look at Arrays.toString(byte[])
如果您的问题是如何将 [0,1,2] 的字节数组的字符串表示形式变为“[0,1,2]”，我建议您查看 Arrays.toString(byte[] )

You can't add Detail Formatters for simple Datatypes like byte.
您不能为简单的数据类型（如byte.

The [B type can be retrieved with byte[].class.
[B 类型可以用 byte[].class 检索。

byte[].class
