Problem 1: Create a PrintChar class that implements Runnable. The constructor should accept a character and an integer as parameters. The run method should print the character the number of times indicated by the integer. Create an application named CharApp.java that instantiates two PrintChar objecs, one passed "A" and 200 and the other one passed"B" and 200. It then instantiates and starts two thread objects. Experiment with the resulting system, using different numerical parameters for PrintChar objects. Create a report (a text file printChar.txt) about the results of your experiments-explain how the multiple threads work in your program
