How do I view different representations of integers in the Eclipse watch window?
提问by jcartano
I would like to view binary (or hex) representations of integers in my watch window in Eclipse when debugging. How do I do this?
我想在调试时在 Eclipse 的监视窗口中查看整数的二进制（或十六进制）表示。我该怎么做呢？

You can do this from Window->Preferences.
您可以从 Window->Preferences 执行此操作。
For primitives, browse to Java->Debug->Primitive Display Options
对于基元，浏览到 Java->Debug->Primitive Display Options
Here there is a checkbox for 'Display Hexadecimal values'. Check this, and you will see both decimal & hexadecimal representations for primitives in the 'value' column under Variables view when debugging.
这里有一个“显示十六进制值”复选框。检查这一点，您将在调试时在变量视图下的“值”列中看到基元的十进制和十六进制表示。
For objects (Integer, Long, etc), browse to Java->Debug->Detail Formatters
对于对象（Integer、Long 等），浏览到 Java->Debug->Detail Formatters
For each type you care about, create a detail formatter that formats the value how you like. For java.lang.Integer, you could use the detail formatter: Integer.toHexString(this)
对于您关心的每种类型，创建一个详细信息格式化程序，以您喜欢的方式格式化值。对于 java.lang.Integer，您可以使用详细信息格式化程序：Integer.toHexString(this)
Make sure your detail formatter is enabled, and you should see the hexadecimal representation in the 'details' area when you select a variable from the Variables view.
确保您的详细信息格式化程序已启用，当您从“变量”视图中选择一个变量时，您应该会在“详细信息”区域中看到十六进制表示。

Your best option is probably to open the Expressionsview (Window -> Show View -> Expressions), right click, choose "Add Watch Expression" and then enter Integer.toBinaryString(yourInt)or Integer.toHexString(yourInt), and click ok.
您最好的选择可能是打开表达式视图（窗口 -> 显示视图 -> 表达式），右键单击，选择“添加监视表达式”，然后输入Integer.toBinaryString(yourInt)或Integer.toHexString(yourInt)，然后单击确定。
