Java Program to Create Two Threads to display number in Ascending and Descending order
Write a Java program to create two threads so one thread will print numbers from ascending number where as second thread will print descending no. between 1 to 15 numbers.
Source Code
class Ascending extends Thread {
public void run() {
for(int i=1; i<=15;i++) {
System.out.println("Ascending Thread : " + i);
}
}
}
class Descending extends Thread {
public void run() {
for(int i=15; i>0;i--) {
System.out.println("Descending Thread : " + i);
}
}
}
public class AscendingDescendingThread {
public static void main(String[] args) {
new Ascending().start();
new Descending().start();
}
}
Output
