Java Practices ide: eclipse env: java 1.8.0
- code code code Thread creation
- code
volatilekeyword (cpu cache / visibility of changes to variables across threads) - code
synchronizedkeyword on method (join()) - code
synchronizedkeyword on method - code Unsynchronized example. 'synchronized method' not work on different objects
- code Producer & Consumer,
synchronizedcode block -- object lock. List size of 1 - code Producer & Consumer,
synchronizedcode block -- object lock. List size of N - code Producer & Consumer, thread save linked list
- code Producer & Consumer, 2 threads add item to list, 2 threads remove item from list
- code Unsynchronized Example. Lock on differet objects.
- code 1 Chef (make food if table empty/block if customer eating) 1 Customer (eat food if food ready/block if food not ready) (Resource 1 table)
- code class
Executor, methodexecute(Runnable) - code class
ExecutorService, methodexecute(Runnable/Callable). - code Sum numbers.
ExecutorService/Runnable/Callable/Future - code CountDownLatch, Max Number
- code CountDownLatch, Sum Numbers
- code CyclicBarrier
- code Dining Philosopher: DeadLock. Semaphore
- code Dining Philosopher: Solve Deadlock, might have Starvation. Semaphore
- [code][multi-philos02] Dining Philosopher: Solve Starvation. ReentrantLock - Fairness
- MySQL setups EmployeeDB Stored Procedure
- MySQL setups BookShelfDB
- code Statement
- code code code PreparedStatement Insert & Select & Update
- code CallableStatement
- code [sql script][] Practice. Bookshelf CRUD operation
- code Java 8 interface feature: default/static method
- code code code Simple demo of functional interface.
- code Print the string which length <= 4 in a list.
- code Check if the length of string is less or equal to 4 (Predicate).
- code Print the length of a string (Function).
- code Generate a random number (Supplier).
- code Print the product that its price is less than 1000.0 (stream api).
- code Print even numbers in the list (stream api).
- code Print employees whose marks are greater than 90, sort the result by employee ID ** (stream api)**.
- code For those who marks are less than 40, give them 5 as the grace marks and then print out the final marks and id and sort them on basis of marks (stream api).
- code Print name of employees who are less than 25 years old and scored more than 40 marks, sort the employees based on their marks (stream api).
- code Using stream with List, Set, Map, Array
- code Employee class: id, name, salary. For each employee: tax on the income salary: less than 3000: 10%. 3000 and 5000: 20%. above 5000: 30% calculate the salary after tax and then find the employee with max salary.
