The following code could deadlock. True Or Fale? void thread1() { pthread_mutex_lock(lock3); pthread_mutex_lock(lock2); pthread_mutex_lock(lock1); // ... pthread_mutex_unlock(lock3); pthread_mutex_unlock(lock2); pthread_mutex_unlock(lock1); } void thread2() { pthread_mutex_lock(lock1); pthread_mutex_lock(lock2); pthread_mutex_lock(lock3); // ... pthread_mutex_unlock(lock3); pthread_mutex_unlock(lock2); pthread_mutex_unlock(lock1); }

i need help with this

How to answer the following questions screenshot shows the ArrayBoundedStack class and StackUnderflowException code  The following expression is balanced: ( ( ( [ ) ] ) ) True or False Our StackUnderflowException code essentially consists of two simple constructors and "packages" and "extends" statements and nothing else. True or False which of these statements is the best representation of the current status of a Stack ADT in the Java Standard Library? A. There is no support for stacks in the library.  B. The library provides a Stack class.  C. The library does not provide a Stack class, but does provide other classes that can be used for the same functionality. D. The library provides a DeQue class that supports stack operations. E. The library provides a legacy Stack class, but it is better to use the DeQue class for stacks.    the ArrayBoundedStack the topIndex variable holds the index of the elements array where the current top of stack is stored. Which of the following code…

1. Show the ListStackADT<T> interface 2. Create a ListStackDataStrucClass<T> with the following methods: defaultconstructor, overloaded constructor, copy constructor, getTop, setTop,isEmpty, ifEmpty (if empty throw the exception), push, peek, pop, toString. 3. Create a private inner class of ListStack<T> called StackNode<T> with thefollowing methods: default constructor, overloaded constructor, copyconstructor, getValue, getNext, setValue, setNext 4. Create a BaseConverter class (non-generic) with the following methods: defaultconstructor, inputPrompt, convert [converts a BaseNumber to a convertedString], convertAll [instantiate a String object] , toString, processAndPrint     5. Create a private inner class BaseNumber. The inner class has the following methods: default constructor, overloaded constructor, getNumber, getBase,setNumber, setBase. [Make your private instance variables in the inner classLong type]. 6. Create a BaseConverterDemo class that only…

TRUE OR FALSE We can use Generics to define a custom generic exception.

Run the program to tell me there is an error, BSTChecker.java:3: error: duplicate class: Node class Node { ^ BSTChecker.java:63: error: class LabProgram is public, should be declared in a file named LabProgram.java public class LabProgram { ^ 2 errors This is my program, please fix it.     import java.util.*; class Node { int key; Node left, right; public Node(int key) { this.key = key; left = right = null; } } class BSTChecker { public static Node checkBSTValidity(Node root) { return checkBSTValidityHelper(root, null, null); } private static Node checkBSTValidityHelper(Node node, Integer min, Integer max) { if (node == null) { return null; } if ((min != null && node.key <= min) || (max != null && node.key >= max)) { return node; } Node leftResult = checkBSTValidityHelper(node.left, min, node.key); if (leftResult != null) { return leftResult; } Node rightResult = checkBSTValidityHelper(node.right, node.key, max); if (rightResult != null) { return rightResult; }…

Please use the information in the second screenshot about the BST class and Node class to create a class BSTApp.  Please make sure to use the following code as a starting point.  import java.util.*; public class BSTTest{public static void main(String[] args) {// perform at least one test on each operation of your BST } private int[] randomArray(int size) {// remove the two linesint[] arr = new int[1];return arr;} // the parameters and return are up to you to define; this method needs to be uncommented// private test() {//// }} Base of class Node public class Node {int key;Node left, right, parent; public Node() {} public Node(int num) {key = num;left = null;right = null;parent = null;}} Base of class BST import java.util.*; class BST {// do not change thisprivate Node root;private ArrayList<Integer> data; // DO NOT MODIFY THIS METHODpublic BST() {root = null;data = new ArrayList<Integer>(0);} // DO NOT MODIFY THIS METHODpublic ArrayList<Integer> getData() {return…
