An application programming interface (API), in the context of Java, is a collection of prewritten packages, classes, and interfaces with their respective methods, fields and constructors. Similar to a user interface, which facilitates interaction between humans and computers, an API serves as a s...
In this program, the classDemoonly implements interfaceInf2, however it has to provide the implementation of all the methods of interfaceInf1as well, because interface Inf2 extends Inf1. Tag or Marker interface in Java An empty interface is known as tag or marker interface. For example Serial...
generally speaking, impossible to make any hard guarantees in the presence of unsynchronized concurrent modification. Fail-fast iterators throw ConcurrentModificationException on a best-effort basis. Therefore, it would be wrong to write a program that depended on this exception for its correctness: the...

Native method programmers should program to the JNI. Programming to the JNI insulates you from unknowns, such as the vendor’s VM that the end user might be running. By conforming to the JNI standard, you will give a native library the best chance to run in a given Java VM. ...
Second, to ensure that the parameter descriptor of a native method, which uses ";" and "[" characters to encode parameter types, can be encoded in a C function name. When a Java program invokes a native method, the VM searches the native library by looking first for the short version ...
