In-Depth Information
NetBeans will indicate compilation errors in our code by underlining the offending
line with a squiggly red line. Placing the caret over the offending code and hitting
Alt+Enter
will allow us to select from a series of suggestions to fix our code.
Sometimes navigating through all the files in a project can be a bit cumbersome,
especially if we know the name of the file we want to open but we are not sure of its
location. Luckily, NetBeans provides the
Shift+Alt+O
keyboard shortcut that allows
us to quickly open any file in our project.
Additional useful keyboard shortcuts include
Shift+Alt+F
, this shortcut quickly
formats our code;
Ctrl+E
erases the current line, much faster than highlighting the
line and hitting backspace. Sometimes we import a class into our code and later
decide not to use it, some of us delete the lines where the class is used but forget to
delete the import line at the top of the source file, NetBeans will generate a warning
about the unused import, hitting
Ctrl+Shift+I
will delete all unused imports in one
fell swoop, plus it will attempt to add any missing imports.
