Long user of eclipse and Java. One issue that i've found with Eclipse, is it seems that there is no easy way to import static members and methods.
Namely, the jUnit fail() method from org.junit.Assert
I create several classes a day, and manually add
import static org.junit.Assert.fail; to the import statements. This is quite annoying. I absolute LOVE using Ctrl+Shift+O to organize my imports, but it still doesn't find static members and methods.
Also, the import does not show up in eclipse.
Funny thing is, is that i've seen it work previously, but i cant recall the variables.
Does anybody know what I need to do to ensure that this static import is always recognized and can be found using Ctrl+Shift+O?
Thanks @qqilihq.
The answer that was accepted does not work with the Organize Imports keyboard shortcut that I preferred in eclipse, but does work for the "hover over" suggestion.

So when should you use static import? Very sparingly! Only use it when you'd otherwise be tempted to declare local copies of constants, or to abuse inheritance (the Constant Interface Antipattern). In other words, use it when you require frequent access to static members from one or two classes.
Importing all of the static members from a class can be particularly harmful to readability; if you need only one or two members, import them individually. Used appropriately, static import can make your program more readable, by removing the boilerplate of repetition of class names.
In Eclipse IDE, you can select the whole reference variable and press Ctrl+Shift+M and it will automatically import that static element using static import in Java.
by Joshua Bloch.) This is considered bad Java programming practice because when a class implements an interface, it becomes part of the class's public API. Implementation details, such as using the static members of another class, should not leak into public APIs.
The static import feature of Java 5 facilitate the java programmer to access any static member of a class directly. There is no need to qualify it by the class name. Less coding is required if you have access any static member of a class oftenly.

Note: You must have the list import permission to import a list. Step 1 – Select File Click on the Static Listyou will be importing into and go to List Actions > Import List. File:Find the file you want to import. File Format:Select the file format from the drop-down.

You can use Ctrl + Shift + M, for example you want to import verify method from Mockito class then
Mockito.verify() // select verify and press Ctrl + Shift + M
This will import verify static method from Mockito class.
