As of NetBeans IDE 6.0 you can now also use Code Completion to generate whole methods. This is useful if you want, for example, to generate a constructor, override methods, or implement methods.

14. Generating Code Using the Code Generation Dialogs: Alt-Insert. Using it we can generate getters, setters, hastcode() and equal() methods

15. The IDE's Java editor provides several ways to add import statements for one or more classes, each offering you a list of possible classes to import when you click on the light bulb error mark or press the appropriate key combinations. In addition, the Editor also displays error hints that assist you with removing imports that aren't needed in your source.

16. Place the cursor on the line of the class that wasn't imported and press Alt+Enter. Alternately, you can click the warning mark in the Annotation Stripe (along Editor's left edge)

17. The IDE's Java editor also provides several other methods for managing imports, such as pressing Ctrl-Shift-I to import multiple types at once and pressing Alt-Shift-I while the cursor is positioned in a type identifier, which enables you to import that specific type

18. To duplicate/move the current line or multiple selected lines: Position the cursor on the line or selection you want to duplicate/move. Press and hold Ctrl-Shift / Alt-Shift, then press either the Up or Down cursor key to copy and paste the code above or below the original line.

19. To instantly Rename all the occurrence of a field, method, variable etc., place the cursor on the filed and press Ctrl+R and then enter the new name. To exit from it press Enter / Esc

Artist got automated

If you are like me, add below changes to their respective files #This is to make tensorflow behave as if it is in v1 File : evaluate.py and ./src/transform.py import tensorflow.compat.v1 as tf tf.disable_v2_behavior() #Image functions are removed from scipy.misc module. so use imageio instead import imageio scipy.misc.imsave(out_path, img) --> imageio.imwrite(out_path, img) img = scipy.misc.imread(src, mode='RGB') --> img = imageio.imread(src, pilmode='RGB') Refer this post on more details on imageio changes Here is the ...
