Chapter 7, Problem 13PP

Program Plan Intro

Covalent bonds

Program plan:

• Include the required header files in the program
• Define the “BondQuery” class
  • Define the “findMatchBonds” method
    • Create an object for “ArrayList”
    • Declare the variable
    • Check the data is in the file
      • Check “datum” is equal to “query”
        • Call the “add” method with an object
      • Increment the “i” value
    • Return the value
  • Define the “printBonds” method
    • Check “index” is in the “bondIndices”
      • Get the input value from the user
  • Define the main method
    • Create an object for “Scanner” class
    • In the “try” block, create an object for “Scanner” class and pass a file name as an argument
      • Declare the variables
      • Create the different objects for “ArrayList”
      • Iterate the loop until it reaches the end of the file
        • Create an object for “Scanner” class
        • Call the methods with different objects
      • Check the “done” value is true
        • Get the input value from the user
        • Check the “option” is equal to “T”
        • • Get the type from the user
          • Call the “findMatchBonds” and “printBonds” methods and store the result in a variable.
            • Check the “option” is equal to “E”
              • Get the energy from the user
              • Call the “findMatchBonds” and “printBonds” methods and store the result in a variable.
            • Check the “option” is equal to “L”
              • Get the length from the user
              • Call the “findMatchBonds” and “printBonds” methods and store the result in a variable.
            • Check the “option” is equal to “Q”
              • Set the “done” value as true.
    • In the “catch” block, display an invalid input message
    • In the “catch” block, display a file not found message.
