JDK 1.9 :  Reactive Streams The Reactive Streams initiative provides a standard for asynchronous stream processing with nonblocking back pressure. A reactive stream provides a way to signal its source to ease production of data when the stream's destination becomes overwhelmed with that data. This signaling capability is like a valve on a water pipe. Closing this valve increases back pressure (the pressure back at the source) while easing the burden on the destination. The initiative's objective is to govern the exchange of stream data across an asynchronous boundary (such as passing data to another thread) while ensuring that the destination isn't forced to buffer arbitrary amounts of data. In other words, back pressure is an integral part of this model in order to allow the queues that mediate between threads to be bounded. Note that the communication of back pressure is handled asynchronously. Reactive Streams focuses on finding a minimal set of interfaces, method...

Java programmers created the double-checked locking to be used with the Singleton creation pattern to limit how much code is synchronized. However, due to some little-known details of the Java memory model, this double-checked locking is not guaranteed to work. Instead of failing consistently, it will fail sporadically. In addition, the reasons for its failure are not obvious and involve intimate details of the Java memory model. These facts make a code failure due to double-checked locking very difficult to track down. Singleton creation:  To understand where the double-checked locking originated, you must understand the common singleton creation. class Singleton {                private static Singleton instance;               private Singleton() {                ...

Problem statement: Given two matrices, the task is to multiply them. Matrices can either be square or rectangular. Example: Input: int m1[][] = {{2, 3, 4}, {5, 6, 7}}; // 2 X 3 matrix int m2[][] = {{1, 2}, {3, 4}, {5, 6}}; // 3 X 2 matrix Output: {{31, 40},{58,76}} public class  MatrixMultiplication  {     public static void main(String args[]) {         int  m1 [][] = {{2, 3, 4}, {5, 6, 7}};    // 2 X 3 matrix         int  m2 [][] = {{1, 2}, {3, 4}, {5, 6}};  // 3 X 2 matrix           int  res [][] = new int[2][2];    // resultant matrix of 2 X 2         for (int  i  = 0;  i  < 2;  i ++) {   //  i  represent row             for (int  j  = 0;  j  < 2;  j ++) {   //  j  represent column     ...

Precondition actions are events that are generated before any operation/event is trigger. A Advisors is basically operational behavior that happens before a certain operation completed.
