Multiple Threads Accessing one method in Java

Concept:
               we want access multiple thread using one method
  Main Method: Several threads are coming different location than handle it using method
                          variable names are represented as global it as unique variable as all thread
  step:-1 synchronized method used to handle multiple thread and execute one by one thread
                        with in the main main method variable names are represented because of step by step execution of threads at the time same variable name represented as different thread
step:-2  multiple threads are coming we want execute step by step by using notify and wait
             notify means it will be report coming  to execution of threads
             wait(2000); means that one thread is able to access resource sharing remaining threads won't be access it will wait 2000msec

                       

//main method: 
public class Addition
{
public synchronized void add(int a,int b,boolean status)
{
Thread t=Thread.currentThread();
String name=t.getName();
System.out.println(name+"Thread started........");
System.out.println(name+"1st number.....="+a);
System.out.println(name+"2nd number.....="+b);
try
{
if(status)
notify();
else
wait(2000);
}
catch(InterruptedException ie)
{
ie.printStackTrace();
}
int c=a+b;
System.out.println(name+"result"+c);
}

}

//example :ThreadA  all the method Local variable represented as a global variable by using this 
public class ThreadA extends Thread
{
int a,b;
boolean status;
Addition aobj;
public ThreadA(int a,int b,boolean status,Addition aobj)
{
this.a=a;
this.b=b;
this.status=status;
this.aobj=aobj;
setName("A");
start();
}
public void run()
{
aobj.add(a,b,status);
}

}
//example :ThreadB  all the method Local variable represented as a global variable by using this 
public class ThreadB extends Thread
{
int a,b;
boolean status;
Addition aobj;
public ThreadB(int a,int b,boolean status,Addition aobj)
{
this.a=a;
this.b=b;
this.status=status;
this.aobj=aobj;
setName("B");
start();
}
public void run()
{
aobj.add(a,b,status);
}

}
//Main PRogram executed..........now we call all thread's ,method and execute it

public class Program
{
public static void main(String[] args)
{
Addition aobj=new Addition();
new ThreadA(12,13,true,aobj);
new ThreadB(50,13,true,aobj);
}
}

JSTL-JSP Standard Tag Library part 1

Evolution of JSTL: Java is a flexible, general-purpose programming language, JavaServer pages(JSP) depends on java but hides some of the hard details of writing full- fledged programs.  The JSP Standards Tag Library(JSTL) builds on top of JSP, making it even easier to use. Architecture : In this figure large web applications are designed using java, JSTL, and othe components like databases. In large applications, it's common for requests from web browser to be handled by a java program called a servlet, which interacts with databases and other Java code on the server. The servlet figures out how it wants a response be printed and then forwards the user to the right JSTL page, which takes care of nothing more than presenting information. As JSP grew in popularity, it became clear that different sites' custom tags fell into familiar, frequently used patterns.  For example, many pages needed to loop over data to print tables and lists. Vendors of JSP ...

Applications of Insulating Materials

All electrical systems require some kind of insulation to prevent short circuits and leaking currents. 3 forms of insulators: solid, liquid and gaseous Performance of these insulators depend on the temperature Classification according to their temperature rating. Impregnation: Letting the solid material absorb some liquid With the advent of new materials, the classification has been modified by International Electrotechnical Commission: The transformer insulation: (a) conductor or turn-to-turn insulation, (b) coil-to-coil insulation, (c) low voltage coil-to-earth insulation, (d) high voltage coil-to-low voltage coil insulation, and (e) high voltage coil-to-ground insulation. Transformer oil -- provides the required dielectric strength and insulation -- cools the transformer by circulating itself through the core and the coil structure. -- should be in the liquid state over the complete operating range of temperatures between -40°C and+50°C. -- gets o...

Java Server page tutorial part 3: JSP Life Cycle

JSP Life Cycle: A JSP life cycle can be defined as the entire process from its creation till the destruction which is similar to a servlet life cycle with an additional step which is required to compile a JSP into servlet. Following are the steps followed by a JSP Container: ◦ Compilation  ◦ Parsing the JSP.  ◦ Turning the JSP into a servlet.  ◦ Compiling  the servlet.  ◦ Initialization ◦ Execution ◦ Cleanup Architecture: 1.       JSP Compilation: When a browser asks for a JSP, the JSP engine first checks to see whether it needs to compile the page.  If the page has never been compiled, or if the JSP has been modified since it was last compiled, the JSP engine compiles the page. The compilation process involves three steps: ◦ Parsing the JSP. ◦ Turning the JSP into a servlet.  ◦ Compiling the servlet.  2.       JSP Initialization: When a container loads a JSP ...
