默认情况下，在 Eclipse 中，当您使用函数或创建对象时，它有助于使用如下参数：
But once it's done, it'll never show up again. Is there any way to call this parameter helper on code that's already written when I point the cursor on the method?
但是一旦完成，它就再也不会出现了。当我将光标指向方法时，有没有办法在已经编写的代码上调用这个参数助手？

Ctrl + Shift + Space will do the trick. It is named Context information in Key preferences.
Ctrl + Shift + Space 可以解决问题。它在 Key 首选项中被命名为上下文信息。

Place the cursor just inside the left parenthesis and press Ctrl+Space(Command+Spaceon Mac) again; Eclipse will show Content Assistagain.
将光标放在左括号内，然后再次按Ctrl+ Space（在 Mac 上为Command+ Space）；Eclipse 将再次显示Content Assist。

You can't get place holders again once they disappeared. But you can get content assist help as said by @E-Riz
一旦它们消失，您就无法再次获得占位符。但是您可以获得@E-Riz所说的内容辅助帮助

When the mouse cursor is in the paranthesis, click Ctrl+Space. It will pop up menu (content assist). If you enter it, it will show the context information as it was at the beginning.
当鼠标光标在括号中时，单击Ctrl+ Space。它将弹出菜单（内容辅助）。如果您输入它，它将显示与开始时一样的上下文信息。
