Explaining Java Technology

Analyzing a Problem and Designing a Solution

• Analyze a problem using object-oriented analysis
• Design classes from which objects will be created
• Developing and Testing a Java Technology Program
• Identify the four components of a class in the Java programming language
• Use the main method in a test class to run a Java technology program from the command line
• Compile and execute a Java technology program

Declaring, Initializing, and Using Variables

• Identify the use the syntax for variables and define the syntax for a variable
• List the eight Java programming language primitive data types
• Declare, initialize, and use variables and constants according to Java programming language guidelines and coding standards
• Modify variable values using operators
• Use promotion and type casting

Creating and Using Objects

• Declare, instantiate, and initialize object reference variables
• Compare how object reference variables are stored in relation to primitive variables
• Use a class (the String class) included in the Java Software Developer Kit (SDK)
• Use the Java 2 Platform, Standard Edition (J2SE[TM]) class library specification to learn about other classes in this application programming

Using Operators and Decision Constructs

• Identify relational and conditional operators
• Create if and if/else constructs
• Use the switch construct

Using Loop Constructs

• Create while loops
• Develop for loops
• Create do/while loops

• Developing and Using Methods
  • Describe the advantages of methods and define worker and calling methods
  • Declare and invoke a method
  • Compare object and static methods
  • Use overloaded methods

  Implementing Encapsulation and Constructors

  • Use encapsulation to protect data
  • Create constructors to initialize objects

  Creating and Using Arrays

  • Code one-dimensional arrays
  • Set array values using length attribute and a loop
  • Pass arguments to the main method for use in a program
  • Create two-dimensional arrays

  Implementing Inheritance

• Define and test your use of inheritance
• Explain abstraction
• Explicitly identify class libraries used in your code
