Please write the program in Java

The function level(a,b,c,d) is a function that divides the largest of its integer arguments by 2. If more than one argument are equal and are the largest, they are divided by 2 For example given a=1,b=2, 4,d=8, levela.b.c.d) changes dto 4 A second call level(a,b,c,d) would change both c and d to 2 a) Write the code of the function level (4 pts) b) To test it, write a program that initializes a = 100: b = 200, 400, 800, then calls levelab.c,d) 10 times in a for loop. In each call display the new values of a, b, c, and d. (6 pts)
