Java Program to Read Text Parameters Assignment Solution.


Write a program to read text parameters in java.

Requirements and Specifications

Description: Using the current code file (attached) fix any errors or add code that is needed to ensure these instructions are met: 1. You have been asked to create a basic histogram in the following format: ^ | |***** (5) |** (2) |*************** (15) |**** (4) |***** (5) |****** (6) |************************* (25) |******** (8) |***** (5) |* (1) +----|----|----|--> The general logic (not all-inclusive) is as follows: 1. Read a text parameter/data file of 10 integers, one per line, into an array. 2. Into a text file write the following: 3. Write the upward-pointing carat “^” and one empty pipe “|” each on individual lines. 4. For each element in the array, do the following: 5. Write a pipe “|”. 6. Write the asterisk “*” as many times as specified by each integer value to create a line of asterisks using a loop. 7. Write the integer value in parentheses to the right of each asterisk bar. 8. Write the final line as one string “+----|----|----|-->” Other: ○ In addition to the file output, include console output using System.out.print for example. Doing so will assist you with debugging. Leave the console output in place in your submission. ○ You are free to vary the number of asterisks per line, within reason. ○ You will need both read and write streams for the parameter/data file and output file, respectively. ○ You will also need to open the files as well as close the files. ○ You will need to specify path and filename information for both files. ○ This Activity can be completed using one class if you prefer. ○ Include appropriate package import declarations as needed. ○ Observe proper commenting/documentation techniques. § Include clearly written comments/documentation to explain the purpose of major blocks of code. § As needed/appropriate, include additional levels of comments/documentation detail to help you understand your code and logic as well as to help your reader understand the same. ○ Observe proper naming conventions for classes, attributes, methods, etc.
