Q&A How can one import two classes with the same name in Java8?

While other JVM languages, such as Groovy, Kotlin and Scala have Python-like import aliasing, Java does not. It's not possible to 're-name' imports, however, when you call a class from a package, ...

Add more information and reword the first paragraphs a bit.

~~Java 8 does not have a method of aliasing, or 're-naming', imports. When you call a class from a package, you can give the full package name before the class name.~~
For example, when calling `FooClass.methodName()` after importing a different copy of `FooClass`, `com.company.utils.FooClass.methodName()` specifies the `FooClass` in the `com.company.utils` package. This allows you to reference multiple copies of `FooClass`.
Full example:
```java
import com.company.special.FooClass;
class BarClass {
public void exampleMethod(){
//Call method1 from FooClass that we imported above
int i = FooClass.method1();
//Call a class named FooClass that is in a different package
String str = com.company.utils.FooClass.methodName();
}
}
```

While other JVM languages, such as [Groovy](https://groovy-lang.org/structure.html#_import_aliasing), [Kotlin](https://kotlinlang.org/docs/packages.html#imports) and [Scala](https://docs.scala-lang.org/tour/packages-and-imports.html#imports) have Python-like import aliasing, Java does not.
It's not possible to 're-name' imports, however, when you call a class from a package, you can use its FQN (Fully Qualified Name), that is, add the full package name before the class name.
For example, when calling `FooClass.methodName()` after importing a different copy of `FooClass`, `com.company.utils.FooClass.methodName()` specifies the `FooClass` in the `com.company.utils` package. This allows you to reference multiple copies of `FooClass`.
Full example:
```java
import com.company.special.FooClass;
class BarClass {
public void exampleMethod(){
//Call method1 from FooClass that we imported above
int i = FooClass.method1();
//Call a class named FooClass that is in a different package
String str = com.company.utils.FooClass.methodName();
}
}
```
