1b) Write a program in Java to do the following:
-Open "file1" and read the first value, n, which is supposed to be an integer describing the size of the upcoming arrays of integer, float, and Boolean values.
-Create one-dimensional arrays of n integer, floating point, and Boolean values.
-Populate the three created arrays by reading their values from file1.
-Declare sum as integer and set it to 0.
-Declare sumf as float and set it to 0.0f.
-Use a for loop to go through each element of the Boolean array, and if an element is “true” then add the corresponding element in the integer array to sum, and also add the corresponding element in the floating-point array to sumf.
-Print all three arrays, sum, and sumf.
