Question
Using NetBeans. Create a threaded class that "races" by counting and displaying the numbers from 1 to 10. Each of the instances of this thread class should have a unique ID (i.e. the first instance should be numbered "1", the next instance should be numbered "2", etc.). Now that you have your threaded class, write a main/driver class that instantiates/spawns 10 instances of your threaded class and runs each of them. When the first thread completes and returns, invoke System.exit() to terminate the program; in so doing, you will be able to determine which thread "won" and achieved it's conclusion first.
This is my program so far but I can't get it to work.
CODE:
package Assignement;
public class Assignment {
public class NumberCounter extends Thread {
@Override
public void run(){
String currThread = Thread.currentThread().getName();
System.out.println(currThread+" is started");
for(int i=1; i<=10; i++){
System.out.print(i+" ");}
System.out.println(currThread+" is Done, Program exits... "+currThread+" won");
System.exit(MAX_PRIORITY);}
}
public class Assignment Main{
public static void AssignmentString[] args{
NumberCounter thread1 = new NumberCounter();
thread1.setName("1");
NumberCounter thread2 = new NumberCounter();
thread1.setName("2");
NumberCounter thread3 = new NumberCounter();
thread1.setName("3");
NumberCounter thread4 = new NumberCounter();
thread1.setName("4");
NumberCounter thread5 = new NumberCounter();
thread1.setName("5");
NumberCounter thread6 = new NumberCounter();
thread1.setName("6");
NumberCounter thread7 = new NumberCounter();
thread1.setName("7");
NumberCounter thread8 = new NumberCounter();
thread1.setName("8");
NumberCounter thread9 = new NumberCounter();
thread1.setName("9");
NumberCounter thread10 = new NumberCounter();
thread1.setName("10");
thread1.start();
thread2.start();
thread3.start();
thread4.start();
thread5.start();
thread6.start();
thread7.start();
thread8.start();
thread9.start();
thread10.start();
}}}
Explanation / Answer
This is ypur main class:
package com.Assignment;
public class Assignment {
public class NumberCounter extends Thread {
@Override
public void run(){
String currThread = Thread.currentThread().getName();
System.out.println(currThread+" is started");
for(int i=1; i<=10; i++){
System.out.print(i+" ");}
System.out.println(currThread+" is Done, Program exits... "+currThread+" won");
System.exit(MAX_PRIORITY);}
}
}
This is your Driver class:
package com.Assignment;
import com.Assignment.Assignment.NumberCounter;
public class AssignmentMain {
public static void main(String[] args){
Assignment a=new Assignment();
NumberCounter thread1 =a.new NumberCounter();
thread1.setName("1");
NumberCounter thread2 = a.new NumberCounter();
thread1.setName("2");
NumberCounter thread3 = a.new NumberCounter();
thread1.setName("3");
NumberCounter thread4 = a.new NumberCounter();
thread1.setName("4");
NumberCounter thread5 = a.new NumberCounter();
thread1.setName("5");
NumberCounter thread6 =a. new NumberCounter();
thread1.setName("6");
NumberCounter thread7 =a. new NumberCounter();
thread1.setName("7");
NumberCounter thread8 =a. new NumberCounter();
thread1.setName("8");
NumberCounter thread9 = a.new NumberCounter();
thread1.setName("9");
NumberCounter thread10 = a.new NumberCounter();
thread1.setName("10");
thread1.start();
thread2.start();
thread3.start();
thread4.start();
thread5.start();
thread6.start();
thread7.start();
thread8.start();
thread9.start();
thread10.start();
}
}
Output:
Thread-1 is started
10 is started
1 2 3 4 5 6 1 7 2 Thread-2 is started
8 9 10 10 is Done, Program exits... 10 won
Thread-7 is started
1 2 3 4 5
