Store record

Program plan:

• Include the required header files in the program
• Define the “BalanceTransaction” class
  • Define the main method
    • Declare the constant variable “EPSILON” with a value
    • Create an object for “Scanner” class
    • Get the filename
    • Get the starting and ending cash amount from the user
    • In the “try” block, create an object for “Scanner” class
      • Declare the variable and set the value
      • Iterate loop until it reaches end of the line
        • Get the values
        • Create an object for “Scanner” class
        • Declare the variables and get the values
        • Check “code” is equal to “R”
        • • Calculate “runningTotal” by adding the amount and “runningTotal” values.
        • Check “code” is equal to “P”
        • • Calculate “runningTotal” by subtracting the amount and “runningTotal” values
        • Check the value of “end” is greater than “runningTotal – EPSILON” and less than “runningTotal + EPSILON”.
        • • Display the statement
        • Otherwise, display the output
    • In the “catch” block, display an invalid input message
    • In the “catch” block, display a file not found message.
