I have a text file with 100 random numbers. I need to create a program (using java) that reads in the numbers from the file into an array. It should then find the largest number in the array and write back out a file called "result.txt". Results should contain the number that was the highest as well as the line number that it was on in the file. I have a text file with 100 random numbers.
