Hi all.Today we are going to create a multithreaded application which will perform the following tasks:
1.First Thread generates random integer every 1 second--(value may be even or odd)
2.Second thread computes the square of the number and prints--(value of first thread is even)
3.Third thread will print the value of cube of number--(value of first thread is odd)
In order to create this application, we require Netbeans IDE.
Follow below steps to create it.
1.Open NetbeansIDE
2.Go to File menu --->NewProject
3.Select Java Application
4.Give it appropriate name according to your requirement
5.Click Next and your new project gets created with the main class whose name is same as your project
6.If you are not in need of the same name for your class refactor it and give the different name for your java class.
In main class, you have to create Object for class A and start its thread.In class A we have thread name, Random class variable, and two thread class variables.
The java.util.Random class instance is used to generate a stream of pseudorandom numbers
Random(): This creates a new random number generator.
The nextInt(int n) method is used to get a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive), drawn from this random number generator's sequence.
Based on the generated random number, and using the following condition we can find whether it is odd or even and perform action accordingly:
if (num % 2 == 0) {
t1 = new Thread(new even(num));
t1.start();
} else {
t2 = new Thread(new odd(num));
t2.start();
}
In even class, we are going to compute the square of the number and in the odd class cube of the number.
The output in Netbeans console is as follows:
