Synchronized run
Suppose we have:
publicclass Synco1extends Thread{
staticint i=0;
Object o;
int j=0;
public Synco1(Object o){
this.o=o;
}
public syncronizedvoid run(){
while (j<5){
//synchronized (o){
System.out.print(Thread.currentThread()+"i before increase "+ i);
try{
Thread.sleep(1000);
}catch(InterruptedException e){System.out.print("Exception");};
j++;
i++;
System.out.println(" ");
System.out.print(Thread.currentThread()+"i afther increase"+ i);
System.out.println(" ");
//}
}
}
}
publicclass Synco1Tester{
/**
* @param args
*/
publicstaticvoid StartThread(Thread t){
t.start();
}
publicstaticvoid main(String[] args){
// TODO Auto-generated method stub
Integer p=new Integer(1);
Synco1 t1=new Synco1(p);
t1.setName("Thread1");
Synco1 t2=new Synco1(p);
t2.setName("Thread2");
StartThread(t1);
StartThread(t2);
}
}
I know the correct way to synchronize is like // syncronize (o) , but whypublic syncronize run (); doesn't synchronize the method run? (excuse the mess word)
