He would obtain a master’s degree from Iowa State University. He turned a life-long interest in plants into a scientific study. For 47 years, he taught at Tuskegee Institute in Alabama. He developed some 300 products that could be derived from peanuts and more than 100 from sweet potatoes and 75 more from pecans.

Complete the Java program given below which searches and display selected daily weather records. The method should handle invalid input, like empty input (including input with only spaces) and non-numeric input. The program should report each error (can use the same message) with an Alert and abort the processing.   You must call the getRecordsWithin() method from the last question and use it properly to receive full credit. Assume the getRecordsWithin() method and all relevant classes work properly, regardless of what you wrote in the last question (i.e. do NOT rewrite implementation of getRecordsWithin() method here. Assume it already exists.).   Requirements: Your program should mimic the given sample sessions. Do NOT modify the given code, otherwise you will lose points. Just add code to appropriate places and specify where it should be added (#1, #2, #3 or additional place(s) in the program). No need to add additional GUI components or handle layout.   Figure 1. Startup screen.     Figure 2-1. A valid search with multiple records returned.     Figure 2-2. A valid search with no records. “Your search returned 0 records” is displayed.     Figure 3-1. An invalid input: empty input (including inputs with only space characters)     Figure 3-2.
