*q3: Write a public static method named q3 that takes no parameters and has return type void. In this method, you may assume there is a file named "properties.csv" with lines in the format "name, opposed, pure,glad" where "name" is a String and all other values are well-formed integers. There is no header line in this file. This method will create a new * file named "output.csv" in the format "name, pure" containing only these two columns from "properties.csv" and...

in Java please (a) Write a static method abbreviate( ) which is passed a String s and an int max. The method returns a new String which contains the content of s abbreviated to at most max characters, but where the last three characters are ellipses (i.e., the characters . . .). For example, if s is "Too bad Spongebob’s not here to enjoy Spongebob not being here. ---Squidward." and max is 10, the method returns the 10-character String "Too...
