• Define the structure of a Java class
• Create executable Java applications with a main method
• Import other Java packages to make them accessible in your code

Working With Java Data Types

Declare and initialize variables Differentiate between object reference variables and Primitive variables Read or write to object fields Explain an Object's Lifecycle (creation, "dereference" and garbage collection) Call methods on objects Manipulate data using the StringBuilder class and its methods Creating and manipulating Strings Using Operators and Decision Constructs Use Java operators Use parenthesis to override operator precedence Test equality between Strings and other objects using == and equals () Create if and if/else constructs Use a switch statement

Creating and Using Arrays
