Question:
Given the following snippet from a JavaCard applet, which constructors are valid? Assume that the appropriate imports of the JavaCard API are there. public class MyApplet extends Applet { private final OwnerPIN ownerPin; // more code here ... }

public MyApplet(byte[] byteArray, short byteOffset, byte byteLength) {
super(byteArray, byteOffset, byteLength);
ownerPin = new OwnerPIN((byte) 1, (byte) 8);
ownerPin.update();
}

public MyApplet(byte[] byteArray, short byteOffset, byte byteLength) {
ownerPin = new OwnerPIN((byte) 1, (byte) 8);
ownerPin.update();
}

public MyApplet(byte[] byteArray, short byteOffset, byte byteLength) {
ownerPin = new OwnerPIN((byte) 8);
ownerPin.update((byte) 8);
}

public MyApplet(byte[] byteArray, short byteOffset, byte byteLength) {
super(byteArray, byteOffset, byteLength);
ownerPin = new OwnerPIN((byte) 1, (byte) 8);
ownerPin.update(byteArray, byteOffset, byteLength);
}

public MyApplet(byte[] byteArray, short byteOffset, byte byteLength) {
ownerPin = new OwnerPIN((byte) 1, (byte) 8);
ownerPin.update(byteArray, byteOffset, byteLength);
}

public MyApplet(byte[] byteArray, short byteOffset, byte byteLength) {
super(byteArray, byteOffset, byteLength);
ownerPin = new OwnerPIN((byte) 8);
ownerPin.update(byteArray, byteOffset, byteLength);
}

public MyApplet(byte[] byteArray, short byteOffset, byte byteLength) {
ownerPin = new OwnerPIN();
ownerPin.update(byteArray);
}
