Statements in method bodies are written only once.

Statements in method bodies cannot be reused from several locations in a program.

Statements in method bodies are hidden from other methods

Divide-and-conquer approach can be used to develop programs from small and simple pieces.

Divide a program into meaningful methods makes the program easier to debug and maintain.

Software reusability uses existing methods as building blocks to create new programs.

Classes System and String are in the package java.lang

We have to use the Java.lang classes by explicitly importing them.

An import declaration is not required if you always refer to a class via its fully qualified class name.

Classes in the same package are implicitly imported into source-code files of other classes in the same package.

When classes that are compiled in the same directory on disk are in the same package, this is known as the default package.

Import declarations involve a package name followed by a dot and the class name.

Reads characters typed by the user until the newline character is encountered.

The newline character is discarded by nextLine.

Pressing Enter inserts a newline character at the end of the characters the user typed.

Return a string containing the characters up to, but not including the new line.

Reads individual words.

Press Enter to submit the string to the program.

The keyword new creates a new object of the class specified to the right of the keyword.

Parentheses to the right of the class name are required.

Parentheses in combination with a class name represent a call to a variable, which is similar to a method but is used only at the time an object is created to initialize the object's data.

It is used to initialize a variable of a class type.

Each new class you create becomes a new type.

A new type created after a new class can be used to declare variables and create objects. 

Class instance creation is used to initialize a variable of a class type.

Parentheses in combination with a class name can represent a call to a constructor.

You can call a method that belongs to another class until you create an object of that class.

A call to a constructor is similar to a call to a method but is used only at the time when an object is created to initialize the object's data.

Any class can contain a main method since the JVM invokes the main method only in the class used to execute the application.

Creates a Meditation package and assigns it to the object myAmbition

Creates a Meditation method and assigns it to the object myAmbition

Creates a Meditation class and assigns it to the object myAmbition

Creates a Meditation object and assigns it to the variable myAmbition

Creates a Meditation variable and assigns it to the instance myAmbition

Creates a Meditation class and assigns it to the instance myAmbition

All import declarations must appear before the first class declaration in the file.

Forgetting to include an import declaration for a class used in the Java program typically results in a compilation error containing a message such as "cannot resolve symbol".

The statement import.java.util.Scanner is to tell the compiler to load package Scanner from class java.util

The import declarations are used by compiler to identify and locate classes used in Java programs.

It will be a syntax error to place an import declaration inside a class declaration's body or after a class declaration.
