Write a program [Order.java] that reads in 2 integers from standard input and prints them, one per line, in sorted order (ascending) to standard output. a) Edit, compile and run this program using the defaults (keyboard and screen) for standard input and standard output. b) Run this program, typing in the input yourself but redirect the output to a file named Order.out. c) Run your program (java Order) three times, but redirect the input of the program so that the first time it gets input from data1.in, the second time from data2.in, etc
