19. jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 19 Write code here … Case 0 – We need a GUI Input: Results to be shown here … Output: send
20. jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 20 void student (){ } Case 1 Input: Method: * student Diamonds: Boxes: Output:
21. jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 21 void student () { Hello world; } Case 2 Input: Method: * student Diamonds: Boxes: * Hello world – variable declaration Output:
22. jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 22 void student () { Hello_world(); } Case 4 Input: Method: * student Diamonds: Boxes: * Hello world – call method Output:
23. jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 23 int x; void student () { world(); for (int x=0; x<10; x++) { hello(); x = x + 1; break; } } Case 4 Input: Output:
24. jgs Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 24 1. Read a File and Split the lines 2. For each line read character by character 3. Concatenate characters, creating the largest STRING possible. Stop when a delimiter, white space, operator, or quotation mark is found. If there are more characters in the line, go to step 2. 4. Bonus points: for each STRING report its TYPE as correspond. E.g., class is a keyword, { is a delimiter, hello is a name (identifier), Student is a name (identifier), + is an operator, extends is a keyword, etc. Part 1
