INTRODUCTION

In Real time applications development, we may get no of problems or bugs or exceptions while

executing or testing the applications, Ti identify the problems and their locations then we have to

trace the applications flow of execution.

To trace applications flow of execution we will use "System.out.println(--)" at basic level.

EX:

Example51

JCode Cell

1
2	assertTrue( true );
3	}
4	}
5	Run Spring Application:
6	Right Click on Project[springapp1].
7	Select "Run As".
8	Select "Maven Test" and see the Result in Console.
9

c) Prepare Test Application

If we execute the above application then we are able to get the following output on console or

command prompt.

Before deposit() method call

logic for deposit

After deposit() method call

Before withdraw() method call

logic for withdraw

After withdraw() method call

Before transfer() method call

logic for transfer

After transfer() method call

If we use System.out.println() method in applications to trace flow of execution then we are able to

get the following problems.

Example52

JCode Cell

1
2	class Transaction{
3	void deposit(){
4	System.out.println("logic for deposit");
5	}
6	void withdraw(){
7	System.out.println("logic for withdraw");
8	}
9	void transfer(){
10	System.out.println("logic for transfer");
11	}
12	}
13	class Test{
14	Transaction tx = new Transaction();
15	System.out.println("Before deposit() method call");
16	tx.deposit()
17	System.out.println("After deposit() method call");
18	-----
19	System.out.println("Before withdraw() method call");
20	tx.withdraw();
21	System.out.println("After withdraw method call");
22	------
23	System.out.println("Before transfer() method call");
24	tx.transfer();
25	System.out.println("After transfer() method call");
26	}
27

Output


logic for deposit
logic for withdraw
logic for transfer
Before deposit() method call
After deposit() method call
Before withdraw() method call
After withdraw method call
Before transfer() method call
After transfer() method call

In Applications, it is not suggestible to write too many no of System.out.println() methods in

applications, because, it will reduce application performance.

enterprise applications.

To overcome all the problems while tracing applications we have to use Logging.

Logging : It is the process of writing log messages during the execution of a program to a central

place. This logging allows you to report and persist error and warning messages as well as info

messages so that the messages can later be retrieved and analyzed.

In general, in java applications, Logging is required

To understand flow of execution in applications
To manage exception messages when Exceptions are occurred in java applications
To manage the event - notification messages in file systems....

Logging Framework: It is a set of classes and interfaces or a product to perform Logging in Java

applications.

EX:

Example57

JCode Cell

1
2	System.out.println() is suitable for simple standalone applications, not for complex
3

c) Prepare Test Application

Advantages of Logging Frameworks:

Problem diagnosis: In ingeneral, in application development, we are able to detect the

problems which are occurred in compilation time or in execution, but, some hidden problems are

existed inside the applications, which may not come in out side direcly, but, they will give effect to

our application execution, in this situation, if we use good Logging Framework then it is possible to

detect the hidden problems quickly and we can fix them easily.

Quick Debugging: Once if we diagnose the problem and if we identify the location of the

problem by using logging framework then it is very simple to fix that problem and it simplifies

Debugging and it able to reduce overall Debugging time.

Easy Maintenance: If we provide good Logging Framework to perform logging in our

applications then it will provide somde description or information about our application which is

usefull to manage our applications easily.

History: In general, all Logging Frameworks are tracing the applications flow of execution and

they are able to store tracing details in a file system, this logging details are usefull to analyze the

problems and to solve the problems.

Cost and Time Saving: Logging Frameworks will simplifies debugging, easy maintenance ,

persisting application information,..... , these qualities of Logging Framework saves time and cost

of the application.

Drawbacks with Logging Frameworks:

Logging Frameworks needs to write some extra code in our java applications, it will

increase overhead to the application.

Logging Frameworks will provide some extra code in our applications, it will increase

application execution time at runtime, it will reduce application performance.

Logging Framework will provide some extra code in application, so that, it will increase

application length.

Poor logging strategies will increase confusion to the developers.

Log4j

Log4J is a reliable, fast and flexible framework written in JAVA to perform logging in Java

applications and it is provided by Apache Software Foundations.
