You can also set it yourself in myeclipse.
Below give you stick a, very whole!

Eclipse is a common shortcut
Eclipse editing function is very powerful, grasp the Eclipse shortcut key function, can greatly improve the development efficiency. Eclipse has the following edit-related shortcuts.
  1. "ALT + /"
  This shortcut key is a good helper for users to edit, can provide users with the content of the auxiliary, do not worry about remembering the names of all methods and attributes, when you can't remember the names of all classes, methods and attributes, more experience the benefits of [ALT+/] shortcut key.
  2. "Ctrl + O"
  Shows an outline of methods and properties in a class, quickly locates methods and properties of a class, and is useful for finding bugs.

  3. "Ctrl + /"
  Quick comments, quick comments or uncomments for the line where the cursor is or the line selected, there may always be a need to comment something or uncomment something while debugging, now you don't need to comment each line repeatedly.

  4. "Ctrl + D"
  Delete the current line, which is one of my favorites, without having to press the delete key so many times to delete a line.

  5. (Ctrl + M)
  Window maximization and restore, the user in the window operation, always feel the current window is small (especially when writing code), now, try [Ctrl+M] shortcut key.

  View and locate the shortcut keys

  In the program, it is not easy to quickly locate the location of the code, quickly find the location of the Bug, Eclipse provides a powerful search function, you can use the following shortcut keys to help complete the search and location of the work.

  1. [Ctrl+K], [Ctrl++Shift+K]
  Quickly look down and up for the selected content, eliminating the need to click the find dialog.

  2. "Ctrl + Shift + T"
  Find the Java class files in the Workspace build path, don't go to the trouble of not finding the classes, and use "*", "?" Equal wildcard.

  3. [Ctrl + Shift + R]
  Corresponding to [Ctrl+Shift+T], find all files (including Java files) in the Workspace (Workspace), or use wildcards.

  4. [Ctrl + Shift + G]
  Find references to classes, methods, and properties. This is a very useful shortcut, for example, to modify the code that references a method, you can use the [Ctrl+Shift+G] shortcut to quickly locate all references to this method.

  5. "Ctrl + Shift + O"
Quickly generate import, when you copy a program from the Internet, do not know how to import into the called class, try [Ctrl+Shift+O] shortcut key, there will be a surprise.

  6. [Ctrl + Shift + F]
  Format code, writing format specification of the code is a required course for every programmer, when you see a piece of code is not pleasing to the eye, selected after pressing the shortcut key (Ctrl+Shift+F) to format this code, if not selected code is the default format of the current file (Java file).

  7. "ALT + Shift + W"
  Finding the path in the project where the current file is located quickly locates the location of the browser view, and this shortcut is useful if you want to find the package where a file is located (especially in larger projects).

  8. [Ctrl + L)
  Locate a line in the current editor, which is also valid for non-java files.

  [Alt+ please ], [Alt+ - ]
  The backward history and forward history are useful for tracking code. The user may have looked up several places of interest, but may not remember, and can use these two shortcuts to locate the order of the lookups.

  10. [F3]
A class, method, and property that quickly locates the cursor position.

  11. "F4"
  Displays the class's inheritance relationships and opens the class inheritance view.

  Eclipse has the following shortcuts for running debugging.

  1. [Ctrl+Shift+B] : set a breakpoint on the current line or cancel the breakpoint set.
  2. [F11] : debug the last executed program.
  3. [Ctrl+F11] : run the last executed program.
  4. [F5] : trace to the method. When the program executes to a method, you can press [F5] to trace to the method.
  5. [F6] : single-step program.
  6. [F7] : after executing the method, return to the last statement that called the method.
  7. [F8] : continue execution to the next breakpoint or the end of the program.

5. The Source - > Generate Getters and Setters -> Ctrl+Shift+. Add the get set method
