Introduction to Java
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It was created by James Gosling and his team at Sun Microsystems, with the first public implementation released in 1995. Java is known for its platform independence, allowing programs written in Java to run on any device that has a Java Virtual Machine (JVM) installed. This feature has made Java a popular choice for developing large-scale applications, including Android apps, web applications, and enterprise software.
How Java Works on Windows 10
On Windows 10, Java is installed as a separate application, which includes the Java Runtime Environment (JRE) and the Java Development Kit (JDK). The JRE provides the libraries, frameworks, and tools required to run Java programs, while the JDK includes additional tools for developing, debugging, and testing Java applications. When you install Java on Windows 10, it installs a JVM, which translates Java bytecode into machine code that your computer’s processor can execute.
