Interactive Java I/O and Debugging

This unit extends foundational Java programming by focusing on debugging control structures and arrays, building simple user interfaces and input/output workflows, and formatting program output. Students will use tools such as JShell, Scanner, JOptionPane, and JFrame, apply core library classes (String, Math, NumberFormat, System), and reflect on career and continued-learning pathways to prepare for further study or entry-level development roles.

Learning Objectives

• Analyze and debug common logic and runtime errors involving arrays, loops, and conditional operators in Java by identifying faults and producing corrected code that satisfies provided test cases.
• Apply Java input/output and user-interface techniques by creating interactive programs that collect user input (using Scanner, JShell, JOptionPane, or System) and present results via console or a basic JFrame interface.
• Demonstrate proficiency with Java core libraries by implementing routines that manipulate Strings, perform Math calculations, and format numeric output using NumberFormat to meet specified output requirements.
• Evaluate programming language options, learning resources, and career pathways by comparing alternatives and producing a personal learning and job-preparation plan (e.g., portfolio, resume bullet points, or roadmap) for continued development as a software developer.
