In Eclipse make a new class file and add this into it, it is very simple so you will have to put the shift in there yourself but you can repeat it with no problem unlike browns simplifying program.
Code:
public class Simplify {
public static void main(String[] args) {
/*
* Replace the shift with the one you want to simplify
* Replace the bytes to the amount of bytes being shifted
*/
int shift = -962490744;
int bytes = 2;
int bits = bytes * 8;
int result = shift % bits;
System.out.println(result);
}
}
The result gets printed onto your console.
