Optimize start up and load time with better server initilization and lazy downloading Java source<\/li>\n<\/ul>\nAs we try our best improving performance, it would still take some time when importing a big Java project to Visual Studio Code. In this case, it would be helpful to show more progress details and let you know what’s actually happening behind the scene. Instead of just showing the percentage of progress, we now added detailed step information into the status, such as inspecting location, configuring project, updating Maven dependencies, refreshing workspace and build workspace to let you know the wait is meaningful.<\/p>\n

More Code Actions<\/h3>\n
Code actions are key to your productivity, so we keep bringing more of them to Visual Studio Code.<\/p>\n
Resolve ambiguous imports<\/h5>\n
To deal with ambiguous imports, you now have a dropdown list to pick the right one. The code line with the unresolved type is also presented to you to help you decide.<\/p>\n
![\"\"](\"https:\/\/devblogs.microsoft.com\/visualstudio\/wp-content\/uploads\/sites\/4\/2019\/05\/java.organize.imports.gif\")
<\/p>\n
Generate hashCode() and equals()<\/h5>\n
Now\u00a0hashCode()<\/code>\u00a0&\u00a0equals()<\/code>\u00a0can be generated with default implementations. All the non-static member variables are listed, and you can customize the generated code using the check list.<\/p>\nThere are two options for you to customize the generated code:<\/p>\n
\n- If you use Java 7+, you can set\u00a0
java.codeGeneration.hashCodeEquals.useJava7Objects<\/code>\u00a0to\u00a0true<\/code>\u00a0to generate shorter code which calls\u00a0Objects.hash<\/code>\u00a0and\u00a0Objects.equals<\/code>.<\/li>\n- You can also set\u00a0
java.codeGeneration.hashCodeEquals.useInstanceof<\/code>\u00a0to check the object type instead of calling\u00a0Object.getClass()<\/code>.<\/li>\n<\/ul>\n![\"\"](\"https:\/\/devblogs.microsoft.com\/visualstudio\/wp-content\/uploads\/sites\/4\/2019\/05\/java.hashcode.equals.gif\")
<\/p>\n
Generate toString()<\/h5>\n
Picking which fields to be included in the toString()<\/code> method and configure its template are all supported with the Generate toString()<\/code> code action.<\/p>\n![\"\"](\"https:\/\/devblogs.microsoft.com\/visualstudio\/wp-content\/uploads\/sites\/4\/2019\/05\/java.generate.tostring.gif\")
<\/p>\n
Extract to local variable<\/h5>\n
To create a new variable (correctly typed) from the return value of an expression, the new quick fix\u00a0extract to local variable<\/code>\u00a0provides a\u00a0quick fix bulb which appears when the cursor stops at the bracket\u00a0<\/span>()<\/code>. The keyboard shortcut is\u00a0<\/span>ctrl + .<\/code><\/p>\n![\"\"](\"https:\/\/devblogs.microsoft.com\/visualstudio\/wp-content\/uploads\/sites\/4\/2019\/05\/extract_variable.gif\")
<\/p>\n
Override\/Implement methods<\/h5>\n
With this new source action, all the cadidates are presented to you with a checklist. Then you can decide what to override or implement.<\/p>\n
![\"\"](\"https:\/\/devblogs.microsoft.com\/visualstudio\/wp-content\/uploads\/sites\/4\/2019\/05\/java.implement.methods.gif\")
<\/p>\n
Add static import<\/h5>\n
You can now convert static functions calls to static imports.<\/p>\n

<\/p>\n
Folding Range<\/h3>\n
Now you can expand or collapse sections of code to make your Java file easy to read. We’ve enabled a couple popular ways for you to specify which code elements should be considered as a region to fold.<\/p>\n

<\/p>\n
<\/h3>\nDebugger Updates<\/h3>\n
Debugger is one of the most used extension in the Java extension family, and we’re excited to show you the improvements below<\/p>\n
Display Logical Structure of Collections<\/h5>\n
The debugger is now showing the logical structure of lists and maps, instead of the physical layout of the collections.\u00a0If you prefer the physical layout view, you can go back by setting\u00a0java.debug.settings.showLogicalStructure<\/code>\u00a0to\u00a0false<\/code>.<\/p>\n![\"\"](\"https:\/\/devblogs.microsoft.com\/visualstudio\/wp-content\/uploads\/sites\/4\/2019\/05\/java.debug_.logical.structure.gif\")
<\/p>\n
Hightlight Exceptions in Editor<\/h5>\n
Exceptions are now highlighted with extra info in the editor window. Before that, you need to hover on the exception to see details. Now the most important info is presented to you right at where it occurs.<\/p>\n
![\"\"](\"https:\/\/devblogs.microsoft.com\/visualstudio\/wp-content\/uploads\/sites\/4\/2019\/05\/java.debug_.exception.view_.gif\")
<\/p>\n
Go to Definition by Clicking Stack Trace in Debug Console<\/h5>\n
When there an exception, you can now click on the stack trace to see the definition of the function calls.<\/p>\n
