What happen when import the same package more than one time in the given class.

[Achyut Behera]

Hi All,

Suppose i have a class name "Animal" in some package;
and one more class "Dog" in some other packages.

What happens if i import the animal class more than one time in Dog class.
The animal class will be loaded twice or what?
Please tell me internally what happens?

Thanks,
Achyut

Have you tried it?

[Joanne Neal]

imports are only used by the java compiler, not by the JVM, so they will have no effect on how many classes are loaded.

If you know the meaning of import statement then you will know what happens if you import the animal class more than one time in Dog class.

The class using import statement

You can use just File

import java.io.File;
public class Test {
 public File file = null;
}

Same class without using import statement
You have to use fully qualified java class name

public class Test {
 public java.io.File file = null;
}

The import means you don't have to write fully quallified java class name.
Its for our convinience to use in coding.
