Name the following-A package that is invoked by default?
The java.lang package is invoked by default by all Java classes. We need not import the classes inside the Java.lang package inside our class. They are automatically imported into all Java classes. Example: java.lang.String If you have to declare an array list the import statement import java.util.ArrayList; must be there in your class declaration. If this import is not present your code using the ArrayList would not compile or work But if you are going to use a String, you can directly use it because it would be automatically imported.

Why to use 'import' in java?
The import statement in Java allows to refer to classes which are declared in other packages to be accessed without referring to the full package name. You do not need any import statement if you are willing to always refer to java.util.List by its full name, and so on for all other classes. But if you want to refer to it as List, you need to import it, so that the compiler knows which List you are referring to. Classes from the java.lang package are automatically imported, so you do not need to explicitly do this, to refer to String, for example.
