I NEED CODING HELP IN JAVA. HERE ARE THE INSTRUCTIONS. PLEASE BE SPECIFIC WHEN CODING.

EXAMPLE INPUT:

dpublic static void main(String[] args) method at the bottom of the class rkLoadDescription with the following functionality: a. Instantiate WorkLoadDescription with the parameter stressTest.txt. b. Print to the console i. Graph Name: \{name of graph in the file, sans the ' { ' ii. Each flow, preceded by the string 'Flow k: ', where k is the flow number starting at 1 , with the flows ordered alphabetically by their name. That is, F2 will be printed before F5. (Note, however, ordering the flows alphabetically is not the same as ordering them numerically, which is what I have usually done in the graph .txt files when creating the flows.) iii.
