Programming Objective: Review of programming and data structures The objective of this assignment is to segment a text into tokens. You can assume that the text contains only printable characters. Each token is a string of length k or less. Additionally, blanks (along with newlines, carriage returns) and punctuation characters (“,.!?”) must be included in a token of unit length. For example, the text “I came, I saw, I left.” can be segmented by k=3 as `I` ` ` `cam` `e` `,` ` ` `I` ` ` `saw` `,` ` ` `I` ` ` `lef` `t` `.` . Additionally, the segmentation can be expressed numerically, where each index represents the place at which each segment occurs for the first time in the text. For example, “I came, I saw, I left.” becomes 1 2 3 4 5 2 1 2 6 5 2 1 2 7 8 9 with the legend: `I`:1, ` `: 2, `cam`: 3, `e`: 4, `,`: 5, `saw`: 6, `lef`: 7, `t`: 8, `.`: 9.
Implement a class Segmentator with the following methods: A constructor Segmentator(Integer segment_length, String filename) that creates a Segmentator associated to the given segment length k and filename. It throws no exception. A List<String segment() method that segments the given file. It throws an appropriate exception in case of I/O or other error. A List<Integer segment() method that segments the given file numerically. It throws an appropriate exception in case of I/O or other error Additionally, implement a main that, given a segment length and file name in the command line, prints the segments (Strings) separated by newlines. The Segmentator class must be documented in JavaDoc. Test cases must be created in JUnit to test all its public methods. Most students have seen JavaDoc and JUnit in 132 or 233: if you did not, it is your responsibility to catch up. The code must compile and run. The class Segmentator will be adapted or reused in future programming assignments. If you are in a non-Java section, it is your responsibility to adapt these specifications to your programming language. Submission Bring a copy to recitation to display on a projector. Additionally, submit an electronic copy of your program to blackboard. Grading This programming assignment is required but does not contribute to your grade.
