compiler generates class files for the jvm, therefore, the java interpreter independent of the platform is responsible for running jvm code on a specific platform. The java virtual machine is not cross-platform. Class file --- the main method of bytecode file: The program entry ensures that the program runs independently and is called by jvm. Data Type: Basic Da

considerable understanding of OO. Third, the attractive Java technology First, let's talk about Java technology. It needs to be explained that, unlike the computer languages commonly heard or used in C, C + +, Visual Basic, Delphi, Java technology refers specifically to the application, not the Java language. Anywa

stack area. 4. JavaHeap 　　　　1) for most applications, Java Heap is the largest memory managed by Java virtual machine. java heap is a memory area shared by all threads. It is created when the VM is started. the only purpose of this memory area is to store object instances, where almost all object instances are allocat

thread-private, as the name implies, differs from the virtual machine stack, which is used to process the native method (Java native method), and the virtual machine stack is the Java method. For the native method, there are many native methods in object, hashcode,wait and so on, the execution of these methods is often aided by the operating system.This area is also likely to throw Stackoverflowerror and O

show that MyException is a subclass of Exception. The try statement block of test () generates an ArithmeticException (the Division is 0), and this exception is caught in catch; then the MyException exception is thrown. The main () method captures and processes the MyException thrown in test. Java exception framework Java exception architecture 1. Throwable is a

= java_values($calcinstance->addAB($term_1,$term_2)); To use these functions, Your PHP application must contain the corresponding PHP class. The most important class is Java. inc, which has a complete list of classes under the directory appName/java. inc, you can get Java class instances, such: $calcinstance=new

PS: The following points, do not understand actually does not matter, just first know, so look good, do not go to the heart, to learn Java again look back, you understand.1.Java is a highly creative object-oriented programming language introduced by Sun in 1995.The father of 2.Java is a Fellow of the Sun Academy: James

>>> and >> are bitwise operators, only valid for integral types (not for floating-point types).When the integer type (low+high) >>1 can replace (Low+high)/2.>>> is the unsigned right-shift operator. If Low+high is a positive integer, these three operations are equivalent.Because of compiler optimizations, their efficiency should be the same (if there is no compiler
