This research examines how Java bridges robotics software development with hardware control. The main goals are to assess Java's performance in robotic system integration, identify its drawbacks, and suggest ways to improve it. JRobotics, LeJOS, and ROSJava, are reviewed using secondary data to determine their effects on hardware interface, real-time performance, and data processing. According to major studies, Java's platform freedom and modularity enable software and hardware integration. Real-time performance, hardware interface, and memory management remain issues. The Real-Time Specification for Java (RTSJ) and specialized libraries provide partial solutions but need additional development. Policy implications include investing in Java library improvements and improving Java developer-robotics researcher cooperation. Research and optimization will improve Java's position in robotics, making robots more efficient and versatile.
