Study Notes
Object Oriented Programming Week 10 Arrays
- The College of Computing and Informatics is teaching Object Oriented Programming with a focus on arrays.
- The week's content includes topics such as primitive vs. reference type, creating, initializing, and modifying arrays, exception handling (try-catch statement), enhanced for statement, passing arrays to methods, pass-by-value vs. pass-by-reference, and multidimensional arrays.
- The goal is to use arrays to solve different Java problems and understand the difference between pass-by-value and pass-by-reference.
- The required reading for this week is Chapter 6 of "Java: How to program: Late Objects", and the recommended reading includes Chapter 3 of "Java The Complete Reference, Eleventh Edition".
- The Java Arrays Tutorial provided by Oracle is also recommended as additional learning material.
- Primitive-type variables can hold only one value of their declared type at a time.
- For example, an int variable can store one integer at a time.
- When a different value is assigned to a primitive-type variable, the previous value is overwritten.
- Reference-type variables, on the other hand, can refer to objects that can hold multiple values.
- Arrays are a type of reference-type variable that can hold multiple values of the same type.
- Exception handling, such as the try-catch statement, is important when working with arrays to handle potential errors or exceptions that may occur.
- Multidimensional arrays allow for the creation of arrays with multiple dimensions, such as a matrix or a table.
