This is not possible.

If you simply want to execute some code at the current place you can use the <code>Expressions</code> view and enter your code as an expression. The methods called by the expression evaluation will run in the current debugging context.

<blockquote>
 Drop to frame - When stepping through your code, you might occasionally step too far, or step over a line you meant to step into.
 Rather than restarting your debug session, you can use the Drop to
 Frame action to quickly go back to the beginning of a method. Select
 the stack frame corresponding to the Java method you wish to restart,
 and select Drop to Frame from Debug view toolbar or the stack frame's
 context menu. The current instruction pointer will be reset to the
 first executable statement in the method. This works for non-top stack
 frames as well.
 
 Note that Drop to frame is only available when debugging with a 1.4 or
 higher VM, or the J9 VM. There are some situations where a JVM may be
 unable to pop the desired frames from the stack. For example, it is
 generally impossible to drop to the bottom frame of the stack or to
 any frame below a native method.

Moving the pointer like in Visual Studio is not possible, however workarounds are:

Going backwards to the beginning of the currently executed method:
Select the method from the debug call stack, right click -> "Drop to frame" 
et voila you're back at the beginning of the method.

Now to reach your desired line select the line by clicking in it and hit ctrl+r or right click the line and select "Run to line".

These techniques are hugely helpful and reduce debugging efforts massively, enjoy!

blocks|key|327279|text|我使用的一个技巧是在您的类中键入一个空格，在安全的位置，例如在注释行中；立即删除它并保存类。这会强制执行点跳到当前方法的开头。我承认，这并不理想，但有时它可以被用作实现您想要的东西的变通方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|327280|虽然在eclipse的默认安装中不能像在Visual+Studio中那样直接移动执行点，但可能存在一个eclipse插件，它可以在某个地方提供该功能。四处找找看。|327281|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

A trick I use is to type a space in your class, somewhere safe such as in the comment line; immediately delete it and save the class. This forces the execution point to jump to the beginning of your current method. Not ideal, I admit, but it can sometimes be used as a workaround to achieve what you want.

Although in the default installation of eclipse it is not possible to do directly move the execution point like in Visual Studio, there may exist an eclipse plugin which provides that functionality somewhere. Have a search around.

blocks|key|3294627|text|我最喜欢ankon的答案，但是另一个选项(只适用于您的特定实例--如果是这样的话)是在if上的断点处停止并修改条件中计算的变量，使其返回false+(在"Variables“视图中，右键单击一个变量，然后单击"Change+Value...")|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3294628|entityMap^0|17|2|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

I like ankon's answer best, but another option (that will only work for your specific instance -- if that) is to stop at a breakpoint on your <code>if</code> and modify the variable(s) evaluated in the conditional such that it returns false (from the "Variables" view, right click on a variable and click "Change Value...")

blocks|key|3294740|text|我认为这在旧版本的eclipse中是完全可能的，我认为我有这样做的记忆，但我猜我只是在Visual+Studio中工作时植入了这种记忆。据我所知，它可能会到达jvm，而不是eclipse本身，有一些页面表明jvm无法处理这一点。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3294741|在我看来，Eclipse比VS好很多很多倍，我在这两个方面都做了大量的工作，自从我发现Eclipse以来，当我不得不在VS中工作时，我总是很痛苦。但是现在没有这个功能肯定是很痛苦的，哈哈。|3294742|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I thought that this was totally possible in older versions of eclipse, I thought I had the memory of doing it, but I guess I just implanted that memory when I worked in Visual Studio. From what I'm reading it might come to the jvm and not eclipse itself, there are pages where it's suggested that the jvm cannot handle that.

In my opinion Eclipse is many many times better than VS, I worked extensively in both and since I discovered Eclipse I was always in pain when I had to work in VS. But not having this feature is definitely hurting right now hehe.

blocks|key|3294753|text|您可以直接跳转到当前调试的方法内部的任何其他方法调用。在当前指令指针下选择一些方法调用，然后使用上下文菜单中的"Step+into+selection“。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3294754|entityMap|0|LINK|mutability|MUTABLE|url|http://blog.deepakazad.com/2012/07/eclipse-tip-stepping-into-selection-and.html^0|1K|J|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

You can jump directly to any other method call inside of the currently debugged method.

blocks|key|324597|text|不幸的是，不能使用指令指针(程序计数器)前进一步，所以你需要做的是引入你自己的“调试”变量，你可以在上面测试-比方说你想绕过一个耗时太长的循环，然后添加一个变量并测试它增加的值，然后用这个变量将循环封装在if中。我知道这很难看，但它可以完成-或者你可以直接在C%2B%2B中开发:-)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|324598|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

unfortunately not possible to step forward with instruction pointer (program counter), so what you need to do instead is to introduce your own "debugging" variables that you can test on - lets say you want to step around a loop that takes too long, then add a variable and test on its increased value and then encapsulate the loop in an if with that variable. I know this is ugly, but it gets it done - or you could just develop in C++ :-)

Put the cursor on the line of your choice and either hit ctrl-R ("Run to line") or right-click and select "Run to line" from the context menu.

Can I move the instruction pointer directly to a line of my choice (within the current method) while debugging a Java program in Eclipse (Galileo)?

It's straightforward to drag the instruction pointer to the desired line within a method in Visual Studio, but I don't see a way to do that in Eclipse (and don't find anything about it in the docs or on google).

Moving the instruction pointer while debugging Java in Eclipse

Visual Studio

Eclipse

Java

在Eclipse (Galileo)中调试程序时，我可以将指令指针直接移动到我选择的行(在当前方法中)吗？在Visual Studio中，将指令指针拖动到方法中所需的行很简单，但在Eclipse中我看不到这样做的方法(在文档或google上也找不到任何关于它的内容)。
