Learning objectives for this review:

• Understand the concept of objects as instances of classes and their role in object-oriented programming in Java
• Demonstrate the ability to create objects using the 'new' keyword and store them in variables of appropriate types in Java
• Execute and understand the purpose of void methods, including how to call them and their effects on program execution in Java
• Apply the concept of passing parameters to void methods and execute such methods with appropriate arguments to achieve desired outcomes in Java
• Demonstrate the ability to call non-void methods in Java and understand how to handle their return values for further use in the program
• Utilize string literals and concatenation operators to manipulate and concatenate string objects in Java
• Identify and apply common string methods, such as length(), substring(), indexOf(), and equals(), to manipulate and extract information from string objects in Java
• Understand the concept of wrapper classes for primitive data types, specifically Integer and Double, and demonstrate proficiency in using them to convert between primitive data types and objects in Java
• Utilize methods provided by the Math class to perform common mathematical operations, such as rounding, exponentiation, trigonometric functions, and finding maximum and minimum values in Java
