You can also see these Eclipse books and courses, to learn more about hidden features of Eclipse IDE. So make sure you do this with your existing Java file before copying text to the text editor.

This is an important step many Eclipse users forget and think that the setting is not working properly. It also replaces existing tabs with spaces. Otherwise, existing tabs will prevent spaces in new lines created with the Enter key. Though make sure you apply a new indentation setting to existing Java files by first selecting all lines using Ctrl + A and then Ctrl+I to apply the current indentation setting.

#HOW TO MAKE A GRADE BOOK WITH JAVA AND UML EDITOR CODE#

When you copy the code to VIM editor or any other UNIX editor e.g emacs the tab is replaced with 8 spaces for indentation, the result will look like the following, much wider code. You can see the code has more spacing than what it had in Eclipse because the default setting for Eclipse was using 4 space width for tabs. Here is how your code will look like before and after when you copy it to a text editor e.g. So, the problem with using tabs is the inconsistent number of spaces, one can choose two spaces width tabs and other programmers can choose 8 spaces width tabs. If you use spaces, you know for sure that your program will have the same spacing no matter which text editor you copy-paste them. from Eclipse to notepad or TextPad, you will suddenly see the tabs are replaced by more or fewer spaces and code is looking much wider or narrower than what it looks on Eclipse IDE. Why? because when you copy-paste the code from one editor to another e.g. Tabs allow you to configure any number of spaces for one tab like you can configure 1 tab = 4 spaces or 2 spaces but that's what many programmers will not like. If it's solely up to you to choose tabs or spaces then it's your choice. If your project is using tabs then you should follow the same setting as nobody wants an SVN commit which says 100% file is changed only to find that tabs were replaced by spaces. The tabs vs space war are is as old as God vs Demons but for me, it's more of a choice and consistency. Learning plugins will be a lot easier after that. In this article, I am going to share how to make Eclipse uses spaces instead of tabs for Java editor, which you use while writing Java programs.ītw, if you are a beginner, I suggest you first go through these Eclipse online courses to understand the core concepts of Eclipse IDE and get yourself familiar with UI and essential features. If you are like many Java programmer who is more comfortable with space than tabs because they give a true sense of spacing, you can always change the Java editor settings to use space instead of tabs in Eclipse.

#HOW TO MAKE A GRADE BOOK WITH JAVA AND UML EDITOR WINDOWS#

UNIX text editors prefer tab is 8 spaces, Windows text editors, and IDEs e.g. This happens because when you copy Java program from Eclipse to a text editor, tabs are converted to spaces and different editor has the different settings of tabs. I see a lot of white spaces which makes the program wider than expected. VIM, Notepad, TextPad, or Edit plus, the indentation goes weird. I use Eclipse IDE extensively to write Java programs for testing and example purposes, but when I copy those programs in any text editors e.g.
