Programming and Problem Solving with Java

Knowledge Goals

• To recognize when noninteractive input/output is appropriate and how it
  differs from interactive input/output


• To know how to read from a text file


• To know how to write to a text file


• To know how to read a numeric value from a file


• To understand the semantics of a whileloop


• To understand when a count-controlled loop is appropriate


• To understand when an event-controlled loop is appropriate


• To recognize how mutable and immutable objects differ

Skill Goals

• Write applications that use data files for input and output


• Construct syntactically correct whileloops


• Construct count-controlled loops with a whilestatement


• Construct event-controlled loops with a whilestatement


• Use the end-of-file condition to control the input of data


• Use flags to control the execution of a whilestatement


• Construct counting loops with a whilestatement


• Construct summing loops with a whilestatement


• Choose the correct type of loop for a given problem


• Construct nested whileloops


• Choose data sets that test a looping application comprehensively
