Java Basic Knowledge Note: This is the main mind map, is simply to say, will only expand the map of the Java keyword, and other later write 1, mind map

2. java keyword

Key words	Describe
Abstract	Abstract methods, modifiers for abstract classes
Asset	Whether the assertion condition satisfies
Boolean	Boolean Data types
Break	Jump out of a loop or label code snippet
Byte	8-bit (BIT) signed data type
Case	A condition for a switch statement
Catch	Match the try with catch exception information
Char	Unicode character data type for 16-bit
Class	Defining classes
Const	Not used
Continue	Do not perform the remainder of this cycle
Default	Default
Do	Loop statement, executed at least once
Double	64-bit double-precision floating-point
Else	If is not the branch that executes immediately
Enum	Enum type
Extend	Represents a class that is a subclass of another class
Final	Indicates that a value cannot be changed after initialization. Indicates that a method cannot be overridden, or that a class cannot have subclasses
Finally	Designed to complete code execution, primarily for program robustness and integrity, code execution, whether or not an exception occurs
Float	32-bit (BIT) single-precision floating-point number
For	For Loop statement
Goto	Not used
If	Conditional statements
Implements	Indicates that a class implements an interface
Import	Import class
Instance	To test whether an object is an instance of a class
Int	32-bit (bit) shaping number
Interface	interface, an abstract type, with only the definition of methods and constants
Long	64-bit (bit) shaping number
Native	Represents methods implemented in non-Java code
New	Assign an instance of a new class, or a new method type
Package	A series of related composition a package
Private	Represents a private field, or method, etc., accessible only from within the class
Protected	Indicates that a field can only be accessed through a class or its subclasses Subclasses or other classes within the same package
Public	Method that represents a shared property
Return	Method return value
Short	16-digit number
Static	Represents the level definition at the class, where all instances are shared
Strictfp	Floating-point comparisons use strict rules
Super	Represents a base class
Switch	SELECT statement
Synchronized	Represents a block of code that can only be accessed by one thread at a time
This	Represents the invocation of the current instance or call another constructor
Throws	Defining exceptions that a method might throw
Transient	Modify fields that do not serialize
Try	Indicates that the code is going to do an exception handling or that a finally mate indicates whether throwing an exception executes the code in the finally
void	Tag method does not return any values
Volatitle	Tag fields may be accessed by multiple threads at the same time without synchronizing
While	While loop
