Pattern-matching in a context unrelated to error-handling:
(in.read, in.read, in.read, in.read) match {
case (0xCA, 0xFE, 0xBA, 0xBE) => println("It's a Java class file!")
case (0xFE, 0xCA, 0xBE, 0xBA) => println("It's in rioplatense!")
case _ => println("Not a clue.")
}
Corresponds to the Java:
List<Integer> input = new ArrayList<Integer>();
for (int a = 0; a < 4; a++)
input.add(in.read());
if (input.equals(Arrays.asList(0xCA, 0xFE, 0xBA, 0xBE)))
System.out.println("It's a Java class file!");
else if (input.equals(Arrays.asList(0xFE, 0xCA, 0xBE, 0xBA))
System.out.println("It's in rioplatense!");
else
System.out.println("Not a clue.");
