Synchronization in Java Example Program

Hi friends, here I have attached Synchronization in Java Example Program. to understand synchronization and synchronized keyword usage in java programming language.

Bank.java

package com.javatraineronline.example;
public class Bank implements Runnable {
private int balance = 100;
@Override
public synchronized void run() {
// printing the thread name
System.out.println(Thread.currentThread().getName()+" came here!!!");
for (int i = 0; i < 10; i++) {
System.out.println(Thread.currentThread().getName()+" doing transaction!!!");
if(balance > 0) {
balance = balance - 10;
} else {
System.out.println("Insufficient balance ...");
}
try {
// Delaying the transaction for 1 second.
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}	
}

ATM.java

package com.javatraineronline.example;
public class ATM {
public static void main(String[] args) {
Bank boa = new Bank();
Thread tom = new Thread(boa);
tom.setName("Tom");
Thread jerry = new Thread(boa);
jerry.setName("Jerry");
// Starting the both thread
tom.start();
jerry.start();
}
}

Output

[su_box title=”Output for ATM.java”]Tom came here!!!
