Java Micro Edition (Java ME) is a subset of the Java programming language designed for developing applications on resource-constrained devices, such as mobile phones, embedded systems, and other small electronics. It provides a flexible environment that allows developers to create applications that can run on various devices with limited memory and processing power. Java ME includes a set of APIs and a virtual machine tailored for these devices, enabling features like user interface design, network connectivity, and data storage. This platform helps developers build portable applications that can operate across different devices, ensuring a consistent user experience.
