How the static method handels
thread safty. As per the explaination read till this time like each thread has its own stack and memory allocated to it.
Even method has single copy of code
How in the following code Object of stringBuffer is actually maintained by
java.
If there is single copy of code. When I am creating the instance of StringBuffer for every thread new instance of StringBuffer is get created but the reference variable is same.
How these tow reference copy of the variable is maintained.
Please any one can answer my querry....?
public class Running extends Thread {
String value;
public Running(String value){
this.value = value ;
}
public void run(){
callstaticMethod(this.value);
// System.out.println("value");
}
public static void
callstaticMethod(String value){
StringBuffer
object = new StringBuffer(value);
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
object.append("2" + value);
System.out.println(object.toString());
}
public static void main(String[] args ){
Thread t1 = new Running("First");
Thread t2 = new Running("Second");
t1.start();
t2.start();
try {
t1.join();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
t2.join();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
