(50pts) Write a Java program A2p1.java with a unique class named A2p1 and no named packages that accepts an arbitrary number of command line arguments each of which is assumed to be an integer. The program also should read from stdin as many integers as there are available. The program then reports the sum of all these integers (from command line arguments and from stdin). A sample run can look like the following (note that number of input integers and the integers themselves can be arbitrary): [kwang@computer] [/temp] $ java A2pl 1-2 3 4 5 The sum is 11. If you run the program with standard input redirection, a sample run can look like the following (assuming the text file someIntegers.txt contains the three integers 3,4,5 on three separate lines): [kwang@computer] [~/temp] $java A2p1 1 -2
