Thread: Question About Some Core Java Classes

Can anyone explain to me with some type of example, how it is the following classes work?

• ClassLoader
• ProcessBuilder
• Thread

I understand what it is happening more or less, but how do they function in a standard Java program? And is the Java Virtual Machine referring to your Java program?

Java is like C++. Only different. In C++ there is the codes that you'll be typing in. On some file. Making the files written in C++. Think of C++ as the back bone software of application programs. Like Apache Tomecat. It is used to build websites as a web server. Java is also like C++, only it is object oriented programming language. And made of class files that can be sent over the internet or Network. A container or JFrame in Java allows pictures to be shown on a screen just like C++ and using windows. Java also has a language. Called Java. Writing programs in Java is done using a platform on Windows. But using Java means making class files that are reusable to send on any machine and on most programming software languages like C++ and making able for computers to communicate. Using Java means using class files to communicate to other computers with just that, Java programming. It has a JVM to be run on. So it runs also on Windows. That is Java. The methods described in Java was C++ before it became Java. About 1974 when C++ was invented. Just about in the 70s.
