I have a sequence of bytes that I have to search for in a set of Binary files using Java.
Example: I'm searching for the byte sequence DEADBEEF (in hex) in a Binary file.
How would I go about doing this in Java? Is there a built-in method, like String.contains() for Binary files?
private int bytesIndexOf(byte[] source, byte[] search, int fromIndex) {
boolean find = false;
int i;
for (i = fromIndex; i < (source.length - search.length); i++) {
if (source[i] == search[0]) {
find = true;
for (int j = 0; j < search.length; j++) {
if (source[i + j] != search[j]) {
find = false;
}
}
}
if (find) {
break;
}
}
if (!find) {
return -1;
}
return i;
}
