I want to set a byte at max or min value, if the value I try to assign is greater. Is there a better way to do it, instead of checking with if statements?
example:
int[] arr = new int[128]; // assume int array is filled with random values
byte[] arr2 = new byte[128];
for (int i = 0; i < arr.length; i++) {
if (arr[i] > 127) {
arr2[i] = 127;
} else if (arr[i] < -128) {
arr2[i] = -128;
} else {
arr2[i] = arr[i];
}
}
is there a way to replace the if/else statement with bitwise operations? Or is there a smarter/faster way to do that?
You could chain Math.min(int, int) and Math.max(int, int) calls. Like,
arr2[i] = (byte) Math.min(127, Math.max(-128, arr[i]));
If arr[i] is less than -128 that will take -128. If the result of that is greater than 127 it will take 127. Which should cover all of your cases.
