When I reformat code with Eclipse, it turns method headers like this:
public void myMethod(String param) {
into method headers like this:
public void myMethod(
String param) {
When I was brought on here I'd never used Eclipse before, and I imported project settings provided by someone else. I have seen that on small new projects I've worked on Eclipse does not do this, so it must be in the settings I've imported. But I've gone through every panel I can find, as well as every hidden file I can find in the workspace, and I can't figure out what is causing this.
How do I turn it off? I don't want a newline before parameters in my method signatures, and I can't imagine why anyone would!
Have a look at Window>Preferences>Java>Code Style>Formatter.
There you can configure almost everything. Your case is found at
Line Wrapping>Method Declarations>Parameters.
In my version of Eclipse, I found the option under Window->Preferences->Java->Code Style->Formatter, then clicked the Edit.. button.
In the new window, go to the Line Wrapping tab and find Method Declarations. You want to change the Line wrapping policy. The Force split check box seems to do the same.
Go into preferences: Java -> Code Style -> Formatter
Restore Defaults or edit what's there.
Additionally, Code Style -> Code Templates will allow you to define generate code formatting.
Note that this is for Eclipse Workspace as a whole, the same Preferences can be accessed under the project preferences if you want to get more fine grained at a per project level.
In eclipse you can define your code formatting use Code Style ,
for MAC System :--> Eclipse --> Preference -- > java--> code Style
for Window System :--> Window->Preferences->Java->Code Style->Formatter
The best way to change your format is to go to Window-> Preferences-> Java-> Code Style-> Formatter. Inside the formatter window, eclipse has a couple of built in styles, but the best way is create a new profile of your own by pressing on New. You can change the format as you please on the edit tab
You can change parentheses and curly braces positioning along with other stuff.

Is there any way to ask the auto-generate methods created by intellij to be generated at the end of the class?
currently when i generate a method (⌥⌘M) it is created right below the function I extracted the method from, and I would like it to be at the end of the file.
Does intellij offer that option?
You can re-arrange the code in IntelliJ after code generation manually even though this does not guarantee that the code will go to the bottom of the file. You can do that by clicking on the "Rearrange" menu item in the "Code" menu:
Another option to re-arrange the code without having to use the menus would be via the "Reformat" file dialogue, by pressing on Windows Ctrl+Shift+Alt+L and by activating in it the "Re-format code" checkbox.
You can change the pattern of code arrangement in the settings in the following dialogue:
There is no such option in Intellij, Once you extract method you can move method up and down using Press Up( ⌥ ⇧ Up) or Down( ⌥ ⇧ Down).
When IntelliJ IDEA detects I'm pasting a piece of copied Java code into a Kotlin file, it offers me to convert the pasted Java to Kotlin. This dialog contains a 'Do not ask again next time checkbox'. I checked this box and selected 'Yes', but now I want to undo my default choice. How do I do this?
I've looked and searched in IntelliJ IDEA's preferences, but haven't found the respective checkbox. Is it actually in the settings, or can I somehow reset default checkbox selections?
Preferences -> Editor -> General -> Smart Keys and somewhere down below you should find your checkbox (took me a while to find this, phew)
I've started working with Intellij (used Eclipse before), and I can't seem to mimic the eclipse formatting
the Eclipse Code Formatter plugin did most of the work, but there are still some differences.
for example:
Original line:
object.add(new ClassForSomething(param1, param2, paramObj.method()));
with IntelliJ formatting:
object.add(new ClassForSomething(param1, param2, paramObj
.method()));
with Eclipse formatting:
object.add(new ClassForSomething(param1, param2,
paramObj.method()));
where do I find the configuration to adjust my intelliJ formatter to what I used to have on the eclipse?
EDIT 1:
I've uploaded my code style --> wrapping and braces configuration
In Preferences > Editor > Code Style > Java > Wrapping and Braces
Method call arguments - Do not wrap
Take priority over call chain wrapping - True
Here's a screenshot:
I reproduced the method splitting behaviour you described and then 'fixed' it with the settings I propose here. However, there are so many formatter configurations, some of which impact each other, that it's possible I haven't reproduced exactly what you are seeing. If so, then I'd suggest trying the following:
Save your Java Code Style to a project specific version then start changing its configuration one item at a time until you find the right one.
Export your Eclipse codestyle (from Eclipse’s Preferences > Java > Code Style > Formatter and export the settings to an XML file via the Export All button) and then import that into IntelliJ (see screenshot below) ... perhaps IntelliJ can work out the correct configuration from the Eclipse formatter.
Check File -> Settings -> Code Style -> Java -> Wrapping and Braces. Make sure "Chained method calls" is set to "Do not wrap" and two squares are unchecked.
Is there a way to have an IDE fix Checkstyle errors automatically without having to fix each manually?
If you are using IntelliJ, you can install the CheckStyle IDEA plugin.
Then import the CheckStyle settings into the editor, and Reformat like normal (Ctrl+Alt+L is default shortcut key).
If you're using Eclipse, yes. You can't correct all problems though. There are two ways:
Right click on the java file in Package Explorer or whatever, and select 'Apply Checkstyle Corrections'.
Click on the error in the problems view, and select 'Quick fix'. This corrects the problem.
Your question is rather vague, but I think what you're asking is if CheckStyle can automatically reformat code that it's checking to fix code layout problems that it finds.
The direct answer here is "no."
However, there are a number of "Java source code formatters" (google that, choose one) that will do what I believe you're asking for.
There is a way to do this every time you save your file but not all warnings in Checkstyle can be fixed automatically.
You can have Checkstyle generate a formatter for you by right clicking on your package in the Package/Project explorer and selecting Checkstyle->Create Formatter-Profile. This will create a new formatter called eclipse-cs [your-package-name] based off of your Checkstyle configuration. You'll find it in the "Active profile" drop-down in the formatter preferences of Eclipse.
You can then set the formatter to run each save by going to Preferences->[Language of Choice]->Editor->Save Actions. Check the "Perform the selected actions on save" and "Format source code" boxes.
I created a feature request for the Eclipse checkstyle plugin to also support quick fixes from within the code editor:
https://sourceforge.net/p/eclipse-cs/feature-requests/150/
I used jalopy. Create Tool to fix the Check style issues.
I have a netbeans project that I imported into eclipse. When I use my code formatting style in eclipse, it breaks the auto generated code in Netbeans. The code is similar to the following.
private void customActionPerformed(java.awt.event.ActionEvent evt) {// GEN-FIRST:event_customActionPerformed
// aaa
}// GEN-LAST:event_customActionPerformed
Is there any way to tell Netbeans to go back and use the correctly named methods? Currently when I am in the GUI Builder, it will not find the method that it had previously generated.
To avoid altering the comments:
Open the preferences (In the Window menu, select Preferences)
In the Preferences tree, go to "Java", "Code Style", "Formatter"
If you only wish to configure a single project, click the "Configure Project Specific Settings" link (looks like a blue URL link)
You may wish to create a "new" profile, copying from the default (or whatever is used for your project)
When you are editing the profile, go to the "Comments" tab, and deselect "Enable Line Comment Formatting". That will prevent spaces from appearing in single line comments.
NetBeans is picky about the comments surrounding guarded blocks At issue here is the space between the // and the GEN.
The GEN needs to immediately follow the comment.
Fails, space before GEN:
// GEN_FIRST:event_customActionPerformed
OK, no space before GEN:
//GEN_FIRST:event_customActionPerformed
