How to convert a Byte Array to an Int Array

Question

I am reading a file by using:

int len = (int)(new File(args[0]).length());
    FileInputStream fis =
        new FileInputStream(args[0]);
    byte buf[] = n         


        

Answer 1

Create a new int array and copy over the values, casting as needed.

int[] arr = new int[len];

for(int i = 0; i < len; i++)
    arr[i] = (int)buf[i];
