I wanted to make a code that printed every second that passes in my timer for a total of 30 seconds (hence why I made a for loop) however it just repeatedly prints 1, so I am guessing that my for loop isn't working and it isn't appending 1 to the variable score. Any suggestions on what I should do? Thanks.
public class TimerSchedule {
public static void main(String[] args) {
// creating timer task, timer
Timer t = new Timer();
TimerTask tt = new TimerTask() {
@Override
public void run() {
for(int i=0; i<30;i++)
{
int score = 0;
score ++;
System.out.println(score);
}
};
};
t.scheduleAtFixedRate(tt,0,1000);
}
}
The reason why it is printing 1
is that you have put the following two statements inside the for
loop:
int score = 0;
System.out.println(score);
The first one is resetting score
in every iteration while the second one prints the updated value of score
in each iteration. The first one should be put outside run()
. Also, you need to cancel the timer when the value of score
reaches 30
.
Given below is the updated code:
import java.util.Timer;
import java.util.TimerTask;
public class Main {
public static void main(String[] args) {
Timer t = new Timer();
TimerTask tt = new TimerTask() {
int score = 0;
@Override
public void run() {
System.out.println(++score);
if (score == 30) {
t.cancel();
}
};
};
t.scheduleAtFixedRate(tt, 0, 1000);
}
}
Output:
1
2
3
