Programming and Problem Solving with Java

Knowledge Goals

• To understand the role of a two-dimensional array in representing a table
  with rows and columns


• To know how floating-point numbers are represented in the computer


• To know how the limited numeric precision of the computer can affect
  calculations


• To understand the relationship between an array and a matrix


• To understand how a two-dimensional array is constructed as an array of arrays

Skill Goals

To be able to:

• Declare a two-dimensional array


• Perform fundamental operations on a two-dimensional array:
  
  
  • Access a component of the array
  
  
  • Initialize the array
  
  
  • Print the values in the array
  
  
  • Process the array by rows
  
  
  • Process the array by columns
  
  
  
  


• Declare a two-dimensional array as a parameter


• Declare and process a multidimensional array


• Use the class DecimalFormatto format output
