Answer:

JList.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION)

Explanation:

JList provides for simultaneous selection of multiple items upon setting the selection mode to MULTIPLE_INTERVAL_SELECTION. The API call for this purpose is:

jlist.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION)

Once the selection mode has been set , we can select set of items in the list as follows:

jlist.setSelectedIndices({1,3,5});

This will select the items with indices 1,3,5 in the list.

int[] vic;

public LFilters(int n, int l) {

lvl = new int[max(n-l+1,0)];

vic = new int[max(n-l+1,0)];

for (int i = 0; i < n-l+1; i++) {

lvl[i] = 0;

}

}

public void lock() {

int me = ThreadID.get();

for (int i = 1; i < n-l+1; i++) { // attempt level i

lvl[me] = i;

vic[i] = me;

// rotate while conflicts exist

int above = l+1;

while (above > l && vic[i] == me) {

above = 0;

for (int k = 0; k < n; k++) {

if (lvl[k] >= i) above++;

}

}

Sedaia [141]

Answer:

Recently, with the new and advanced hacking algorithms and affordable high-performance computers available to adversaries, the 36 character computer suggested passwords can easily be insecure.

Explanation:

The 8 length passwords generated pseudo-randomly by computers are not secure as there are new algorithms like the brute force algorithm that can dynamically obtain the passwords by looping through the password length and comparing all 36 characters to get the right one.

And also, the use of high-performance computers makes these algorithms effective
