in java but withou using try&catch, a thumbs up will be give

Write a program in a class named SumFiles that gets 2 or more command-line arguments. The last argument is a file that the program will send its output to. The other arguments are names of input files that already exist and that contain integers. The program opens each of the existing input files, in the order given by the arguments, and reads and sums all the integers of each file, writing the name of the input file followed by its sum to the output file (given by the last argument).EXAMPLE: If the program were invoked like this: a.out fileA fileB fileZZZand if the content of fileA was "3 98 " and that of fileB "4 1 " then the output written to fileZZZ would be:fileA 20 fileB 5 Additional Notes: fileB and fileA should not be modified
