Write a java program that reads data from three separate data files data1.txt, data2.txt, and data3.txt (use Notepad for the data). Can you use command code for this to explain whats going on using arrays. Also, step by step process on how you got it to work on excel. Thank you very much in advance!

data1

data2

data3

Each of these files represents sampled data from a sensor at intervals of 0.5 seconds.

The program should read all data from the three separate files in the correct sequence (data1.txt, then data2.txt then data3.txt) and store into array y. Create an array x to contain the time values starting from -6 and increment by 0.5.

Create a file combined_data.csv that combines both the x and y values (separated by a comma) as show below:

36 30.25 25 20.25 16 12.25 6.25 695442 27133551 30981216 0205 011358440 . * .202 202020 000000124332062 . . . . . .260506 211964469112233 050505050505050 001122334455667 655443322110 Open the 'combined data.csv' file in Excel and plot the sensor data vs time 40 35 30 25 20 15 10
