""Exploring the World of Java: An Introduction to Its Tools, Frameworks, and Career Opportunities"
INTRODUCTION: Java is a popular object-oriented programming language that has been around for more than two decades. It was first released by Sun Microsystems in 1995 and is now owned by Oracle Corporation. The language was designed to be platform-independent, meaning that Java code can be written once and run on any platform that supports Java. This feature has made Java a popular choice for developing cross-platform applications.

Java Development Tools

Java developers use a variety of development tools to write, test, and debug Java code. Some of the most popular Java development tools include Eclipse, IntelliJ IDEA, and NetBeans. These tools offer a range of features, such as code completion, debugging, and code profiling, that make it easier for developers to write high-quality code.
