Java - Threads in Java
Thread is the feature of mostly languages including Java. Threads allow the
program to perform multiple tasks simultaneously. Process speed can be increased
by using threads because the thread can stop or suspend a specific running
process and start or resume the suspended processes. Multitasking or
multiprogramming is delivered through the running of multiple threads
concurrently. If your computer does not have multi-processors then the
multi-threads really do not run concurrently.
This example illustrates how to create a thread and how to implement the
thread. In this example we will see that the program prints numbers from 1 to 10
line by line after 5 seconds which has been declared in the sleep
function of the thread class. Sleep function
contains the sleeping time in millisecond and in this program sleep
function has contained 5000 millisecond mean 5 second time. There is sleep
function must caught by the InterruptedException.
So, this program used the InterruptedException
which tells something the user if thread is failed or interrupted.
Here is the code of the program :
public class Threads{
public static void main(String[] args){
Thread th = new Thread();
System.out.println("Numbers are printing line by line after 5 seconds : ");
try{
for(int i = 1;i <= 10;i++)
{
System.out.println(i);
th.sleep(5000);
}
}
catch(InterruptedException e){
System.out.println("Thread interrupted!");
e.printStackTrace();
}
}
}
