$*$IN JAVA$*$ Develop a program that computes and records an individual's Body Mass Index $($BMI$)$ and stores it in a file. The BMI can be determined using two distinct formulas, one for the Metric system and another for the Imperial system:

Metric formula:

BMI $=$ kilograms$/$ meters$2$

Imperial formula:

BMI $=($Pounds x $703)/$ inches$2$

The program must incorporate two separate functions, one for the Metric system and the other for the Imperial system. After calculating the BMI within these functions, return the value to the main function. In the main function, store this computed value in a file named "BMI.txt$"$ along with the individual's name, following the format shown in the provided screenshots. Subsequent program executions should append new values to the bottom of the text file, preserving a record of prior BMI calculations, as illustrated in the last screenshot.
