Download Java Runtime Environment 1. Java can run applications developed using the java programming language and set of development tools. The JVM is a crucial component of the Java platform. The availability of JVMs on many types of hardware and software platforms enables Java to function both as middleware and a platform in its own right. Hence the expression . As of 2. 00. 6, changes to specification to support changes proposed to the class file format (JSR 2.

JSR 9. 24. The specification for the JVM is published in book form, known as.

Understanding JVM Internals . The most important element of the JRE is Java Virtual Machine (JVM), which analyzes and executes Java byte code. Java developers do not need to know how JVM works. So many great applications and libraries have already been developed without developers understanding JVM deeply. However, if you understand JVM, you will understand Java more, and will be able to solve the problems which seem to be so simple but unsolvable.

Thus, in this article I will explain how JVM works, its structure, how it executes Java bytecode, the order of execution, examples of common mistakes and their solutions, as well as the new features in Java SE 7 Edition. Virtual Machine. The JRE is composed of the Java API and the JVM.

The role of the JVM is to read the Java application through the Class Loader and execute it along with the Java API. A virtual machine (VM) is a software implementation of a machine (i. Originally, Java was designed to run based on a virtual machine separated from a physical machine for implementing WORA (Write Once Run Anywhere), although this goal has been mostly forgotten. Therefore, the JVM runs on all kinds of hardware to execute the Java Bytecode without changing the Java execution code.

The features of JVM are as follows: Stack- based virtual machine: The most popular computer architectures such as Intel x. Architecture and ARM Architecture run based on a register.

However, JVM runs based on a stack. Symbolic reference: All types (class and interface) except for primitive data types are referred to through symbolic reference, instead of through explicit memory address- based reference. Garbage collection: A class instance is explicitly created by the user code and automatically destroyed by garbage collection. Guarantees platform independence by clearly defining the primitive data type: A traditional language such as C/C++ has different int type size according to the platform. The JVM clearly defines the primitive data type to maintain its compatibility and guarantee platform independence. Network byte order: The Java class file uses the network byte order.

To maintain platform independence between the little endian used by Intel x. Architecture and the big endian used by the RISC Series Architecture, a fixed byte order must be kept. Therefore, JVM uses the network byte order, which is used for network transfer. The network byte order is the big endian. Sun Microsystems developed Java. However, any vendor can develop and provide a JVM by following the Java Virtual Machine Specification.

For this reason, there are various JVMs, including Oracle Hotspot JVM and IBM JVM. The Dalvik VM in Google's Android operating system is a kind of JVM, though it does not follow the Java Virtual Machine Specification. Unlike Java VMs, which are stack machines, the Dalvik VM is a register- based architecture. Java bytecode is also converted into an register- based instruction set used by the Dalvik VM. Java bytecode. To implement WORA, the JVM uses Java bytecode, a middle- language between Java (user language) and the machine language. This Java bytecode is the smallest unit that deploys the Java code.

Before explaining the Java bytecode, let's take a look at it. This case is a summary of a real example that has occurred in development process. Symptom. An application that had been running successfully no longer runs.

Moreover, returns the following error after the library has been updated. Exception in thread . However, the application code has not been changed, since it does not use the return value of the add. User() method. At first glance, the com. User. Admin. add. User() method seems to still exist, but if so, why does No.

Such. Method. Error occur? Reasons. The reason is that the application code has not been compiled to a new library. In other words, the application code seems to invoke methods regardless of the return value.

However, the compiled class file indicates the method that has a return value. You will see this through the following error message. Computer Software Programming Engineer. No. Such. Method. Error: com. nhn. user. User. Admin. add. User(Ljava/lang/String; )VNo.

Such. Method. Error has occurred since the . In the expression of Java Bytecode, . This means that the add. User() method returns one java/lang/String object as a parameter. In the library of this case, the parameter has not been changed, so it is normal.

In the expression of Java Bytecode, . In short, the error message means that one java. String object has been returned as a parameter and the com.
