Java Exam II
Java Exam II
Covers all material from the semester, including input/output, exception handling, math expressions, conditional statements (if/else, switch), loops (while, do-while, for), flowcharts/CA, methods & scope, documentation (Javadoc), version control (git), IDEs (Eclipse), arrays/ArrayLists, and basic file I/O (reading).
Exception Handling
Exception Handling
A programming technique in Java for handling errors that may occur during program execution. It's accomplished using try-catch blocks to manage exceptions (errors) that might happen and provide graceful recovery.
Input/Output (I/O) in Java
Input/Output (I/O) in Java
The process of reading data from the user or a file into your program (input) and displaying data on the console (output), or writing to a file (output).
