I want a program can read in three integers then prints out their sum and product and average
for my input,it should have one or more lines of numbers that have been typed in by the user. Each line is to
have exactly three real numbers.I would like to sue in.nextDouble() to read a number and after reading there doubles. how do i discard rest of spaces?
for my output it should have for each line,the numbers that had been read in separated by a single space followed by their sum, product, and
average separated by a space.
Each number is to be printed using "%.2e" format. I would use S.O.P("%.2e %.2e\n", num1, num2);

    Capitalization JAVA In this program, you will read a file line-by-line. For each line of data (a string), you will process the words (or tokens) of that line one at a time. Your program will capitalize each word and print them to the screen separated by a single space. You will then print a single linefeed (i.e., newline character) after processing each line – thus your program will maintain the same line breaks as the input file. Your program should...
