• MOD-1.C Identify, using its signature, the correct constructor being called.
• MOD-1.D For creating objects: a. Create objects by calling constructors without parameters. b. Create objects by calling constructors with parameters.
• VAR-1.D Define variables of the correct types to represent reference data.

Lesson 2: Calling a Void Method

• MOD-1.E Call non-static void methods without parameters.

Lesson 3: Calling a Void Method with Parameters

• MOD-1.F Call non-static void methods with parameters.

Lesson 4: Calling a Non-Void Method

• MOD-1.G Call non-static non-void methods with or without parameters.

Lesson 5: String Objects

• VAR-1.E For String class: a. Create String objects. b. Call String methods.

Lesson 6: String Methods

• VAR-1.E For String class: a. Create String objects. b. Call String methods.

Lesson 7: Wrapper Classes
