It is important that the main method has a strictly defined signature it is public, static, does not return any value void , with a parameter in the form of an array of strings String args. Otherwise, the virtual machine simply will not find it. Our main method contains only one line, which outputs the text Hello, world! On the console! Before compiling, save the written code to a file. The file name must match the class name up to uppercase . So, we open a command prompt or terminal and first call the compiler javac and then the JVM virtual machine java.
Users User> javac HelloWorld java C Users User> java HelloWorld Hello world! After compilation, a HelloWorld class binary file will appear containing the bytecode. The name of this file Australia Mobile Number List without the extension is passed as a parameter when calling the virtual machine. As a result, we see the line Hello, world! This is the result of the program. Java Programming Language Version History June Beginning of the Java programming language project. JDK. January JDK. February J SE. December J SE. May J SE.

Java SE July Java SE March , Java SE September , Java cross platform language Java code written on one platform that is, the operating system can run unchanged on other platforms. The Java Virtual Machine JVM is used to run Java. The JVM processes the byte code, then the processor processes the code received from the JVM. All virtual machines work the same, so the same code runs the same on all operating systems, making Java a cross platform programming language.
