To access the classes which are present in other packages, we have to import the package to our program using the keyword 'import'. Eg: import packagename.subpackage.Class; OR import packagename.subpackage.*; /*Adds all the class which are present in package*/ 'extends' is the keyword used to inherit the classes defined in other packages.

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.
"Java This keyword" is a reference to the current object, it is very helpful when you need to refer an instance of a particular Object from its available methods or using it's constructor, also "this" keyword helps us to avoid naming conflicts.The following are different ways to use java this keyword1) Using with instance variable2) Using with Constructor3) Pass / Return current instanceUsing with instance variableUsing this keyword inside a method or constructor it will use instance variable instead of local variable, in the absence of this keyword it will use local variableUsing with instance variableUsing this keyword inside a method or constructor it will use instance variable instead of local variable, in the absence of this keyword it will use local variableUsing with ConstructorUsing this keyword inside constructor like followingthis("Sony", 20); it will call the constructor having same parameter
No. The keyword super is used to refer to the parent class instance while the keyword this is used to refer to the current class instance. You need to learn about Inheritance and Object creation using constructors to learn more about these keywords and their use

Delete keyword
The import keyword in Java is used to tell the Java compiler where to find different classes and packages.java.util.Date is the location of the Date class: Date is a member of the util package, which is a member of the java package.
we cannot use the staic keyword inside the method... But we can use the final keyword inside the method....
Yes, anywhere that you can normally declare an object you can use the static keyword to make that object static.int main (){static Object o;}

You can use many keyword for link building, but you should use an LSI keyword so, you will better to give links on your keyword. The idea is to find as many qualifiers as possible that fit your audience. http://socialseoteam.com/link-building-2015.php
