The import statement is to tell the compiler and the JVM the paths what the other classes referenced by this class are present and where to look for them.

For ex:

import java.util.*;

The above statment imports the java.util package and all classes inside the package are available for use inside the class that contains this line.

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.


The import statement is always the first noncomment statement in a Java program file?

False. If your class belongs to a package, the package statement should be the first statement. Plus, it's possible that you're not using any resources outside the default java.lang package, and would have no need to import any additional packages.


Import statement in java?

import PackageName.SubPackage.ClassName.SubClass; or import PackageName.SubPackage.*; \\ this will import any class in the package note : it's very simple, consider the packages are like folders, as the are.

Why doesn't Java use header files?

A header file in C is used to import the features of parent classes in our class. The same feature is provided by the import statement in Java hence the header files are not used.

What is the difference between implicit import statements and explicit import statements?

In some cases, many explicit import statements equal only one implicit import statement. Would you rather type this:import java.util.ArrayList;import java.util.List;import java.util.Collection;import java.util.LinkedList;import java.util.Queue;import java.util.HashMap;import java.util.Map;import java.util.PriorityQueue;than this:import java.util.*;Well, the first group of statements is functionally equivalent to the first one.

How do you import such classes if the classes are needed to be imported first before it can be used in program?

To import a class in a program, you typically include an import statement at the top of your code. The syntax for importing a class is: import package_name.class_name;. For example, if you want to import a class called "Person" from a package called "com.example", you would write: import com.example.Person;. Once the class is imported, you can use it in your program by creating objects of that class or accessing its static members.

What does this mean import com.otherwise.jurtle.?

The "import" statement in Java imports names from some other package into the current context. So, if there was a class called com.otherwise.jurtle.SomeClass, you would have to refer to it by the full name, unless you imported it. The import can be done specifically for one class: import com.otherwise.jurtle.SomeClass; or for everything in a package: import com.otherwise.jurtle.*; In Java 5 and up, you can also import all the static functions from a class: import static com.otherwise.jurtle.SomeClass.*; The "com.otherwise.jurtle" part is called the package identifier. The general practice is for a company to reverse its domain name for this. So jurtle.otherwise.com becomes com.otherwise.jurtle.


What does import java.awt.event mean?

The statement import java.awt.event is a Java import statement that allows a program to use classes and interfaces from the java.awt.event package, which contains classes for handling event-driven programming, such as user interactions with GUI components. This package includes event listener interfaces and event classes for various types of events, such as mouse clicks, key presses, and window actions. By importing this package, developers can easily implement event handling in their Java applications.
