I have two options to execute my program (I need to have Out_str as a result).
Option 1:
Out_str = "";
for (i = 1; i <= 20000; i++) {
Out_str = Out_str + "word";
}
Option2:
Runnable runnable1 = new Runnable() {
public void run() {
Out_str1 = "";
for (i1 = 1; i1 <= 10000; i1++) {
Out_str1 = Out_str1 + "word";
}
}
};
Runnable runnable2 = new Runnable() {
public void run() {
Out_str2 = "";
for (i2 = 1; i2 <= 10000; i2++) {
Out_str2 = Out_str2 + "word";
}
}
};
Thread thread1 = new Thread(runnable1);
thread1.start();
Thread thread2 = new Thread(runnable2);
thread2.start();
Why using threads does not make my program execute faster (in both cases the execution takes approx 12 sec with my laptop)? What shall I use in this case (to make it faster to obtain Out_str)? Will using services make help in this case?
The Thread allows you to run processes concurrently. You haven't gained any processing power though, with equal priority your threads would be run in a round-robin way I would guess.
