How Java Threads communicate with each other? |
|
Answer» Inter-thread communication involves the communication of Java threads with each other. The three methods are Java that are used to IMPLEMENT inter-thread communication are given as follows:
This method causes the CURRENT thread to release the lock. This is done until a specific amount of time has passed or another thread calls the notify() or notifyAll() method for this OBJECT.
This method wakes a SINGLE thread out of multiple threads on the current object’s monitor. The choice of thread is arbitrary.
This method wakes up all the threads that are on the current object’s monitor. A program that demonstrates inter-thread communication in Java is given as follows: class BankCustomer { int balAmount = 10000; synchronized void withdrawMoney(int amount) { System.out.println("Withdrawing money"); balAmount -= amount; System.out.println("The balance amount is: " + balAmount); } synchronized void depositMoney(int amount) { System.out.println("Depositing money"); balAmount += amount; System.out.println("The balance amount is: " + balAmount); notify(); } } public class Demo { public static void main(String args[]) { final BankCustomer cust = new BankCustomer(); new Thread() { public void run() { cust.withdrawMoney(5000); } }.start(); new Thread() { public void run() { cust.depositMoney(2000); } }.start(); } }The output of the above program is as follows: Withdrawing money The balance amount is: 5000 Depositing money The balance amount is: 7000 |
