Given is Parser.java. Methods must accept tokens appropriately and generates OperationNode or returns partial result. I need the methods to be created for the following:  -Post Increment/Decrement -Exponents -Factor -Term -Expression -Concatenation -Boolean Compare -Match -Array Membership -And -Or -Ternary -Assignment Parser.java import java.text.ParseException; import java.util.LinkedList; import java.util.List; import java.util.Optional; import javax.swing.ActionMap;   public class Parser {       private TokenHandler tokenHandler;     private LinkedList tokens;       public Parser(LinkedList tokens) {         this.tokenHandler = new TokenHandler(tokens);         this.tokens = tokens;     }     public boolean AcceptSeparators() {         boolean foundSeparator = false;         while (tokenHandler.MoreTokens()) {             Optional currentToken = tokenHandler.getCurrentToken();             if (currentToken.isPresent() && (currentToken.get().getType() == Token.TokenType.NEWLINE || currentToken.get().getType() == Token.TokenType.SEMICOLON)) {                 tokenHandler.consumeMatchedToken();                 foundSeparator = true;             } else {                 break;             }         }         return foundSeparator;     }     public ProgramNode Parse() throws ParseException {                 }         return false;     }     private boolean parseAction(ProgramNode programNode) {         Optional functionNameToken = tokenHandler.getCurrentToken();         if (tokenHandler.MatchAndRemove(Token.TokenType.IDENTIFIER) != null) {             ActionMap actionMap = new ActionMap();             programNode.addNode(actionMap);             AcceptSeparators();             return true;         }         return false;     } public VariableReferenceNode ParseLValueVariable(String variableName) {     return new VariableReferenceNode(variableName, Optional.empty()); } public VariableReferenceNode ParseLValueArray(String variableName, int index) {     return new VariableReferenceNode(variableName, Optional.of(index)); }   public OperationNode ParseLValueDollar() {     return new OperationNode("$");  }   public ConstantNode ParseBottomLevelConstantsAndPatterns() { ConstantNodePatternNode node = new ConstantOrNodePatternNode(); node.setConstant("example");     node.setPattern("PATTERN_1");     return node;  }   public OperationNode ParseBottomLevelParenthesis() throws ParseException {     if (tokenHandler.MatchAndRemove(Token.TokenType.LPAREN) != null) {         OperationNode operationNode = ParseExpression();         if (tokenHandler.MatchAndRemove(Token.TokenType.RPAREN) != null) {             return operationNode;         } else {             throw new ParseException("Expected ')'", tokenHandler.getCurrentToken().getStart());         }         return null;      } else {         throw new ParseException("Expected '('", tokenHandler.getCurrentToken().getStart());     } } private OperationNode ParsePower() throws ParseException {     OperationNode left = ParseBottomLevelParenthesis();     while (true) {         Optional op = tokenHandler.MatchAndRemove(Token.TokenType.CARROT);         if (op.isEmpty()) {             return left;         }         OperationNode right = ParseBottomLevelParenthesis();         left = new OperationNode(left, op.get(), right);     } } private OperationNode ParseLogicalAnd() throws ParseException {     OperationNode left = ParseComparison();     while (true) {         Optional op = tokenHandler.MatchAndRemove(Token.TokenType.AND);         if (op.isEmpty()) {             return left;         }         OperationNode right = ParseComparison();         left = new OperationNode(left, op.get(), right);     } } private OperationNode ParseComparison() throws ParseException {     OperationNode left = ParseAdditionOrSubtraction();     while (true) {         Optional op = tokenHandler.MatchAndRemove(Token.TokenType.EQUAL)                 .or(() -> tokenHandler.MatchAndRemove(Token.TokenType.NOT_EQUAL))                 .or(() -> tokenHandler.MatchAndRemove(Token.TokenType.LESS_THAN))                 .or(() -> tokenHandler.MatchAndRemove(Token.TokenType.LESS_THAN_OR_EQUAL))                 .or(() -> tokenHandler.MatchAndRemove(Token.TokenType.GREATER_THAN))                 .or(() -> tokenHandler.MatchAndRemove(Token.TokenType.GREATER_THAN_OR_EQUAL));         if (op.isEmpty()) {             return left;         }         OperationNode right = ParseAdditionOrSubtraction();         left = new OperationNode(left, op.get(), right);     } }     private OperationNode ParseAdditionOrSubtraction() { return null; }   private OperationNode ParseLogicalOr() throws ParseException {     OperationNode left = ParseLogicalAnd();

Consider the following implementation of binarySearch: public static bool binarySearch(int[] a, int item) { int first = 0; int last = a.length - 1; while( first <= last) { int mid = (first + last)/2; if(a[mid] item) return true; else if (a[mid] < item) first = mid + 1; else last = mid - 1; } return false; == } how many times is the line of code int mid = (first + last)/2; executed when it is called with a = {2, 3, 5, 7, 11, 13,17, 19, 23, 29, 31, 37} and item = 2?

Your crazy boss has assigned you to write a linear array-based implementation of the IQueue interface for use in all the company's software. You've tried explaining why that's a bad idea with logic and math, but to no avail. So - suppress your inner turmoil and complete the add() and remove() methods of the AQueue class and identify the runtime order of each of your methods. /** A minimal queue interface */ public interface IQueue { /** Add element to the end of the queue */ public void add(E element); /** Remove and return element from the front of the queue * @returns fırst element * @throws NoSuchElementException if queue is empty */ public E remove(); /** Not an ideal Queue */ public class AQueue implements IQueue{ private El) array: private int rear; public AQueue(){ array = (E[)(new Object[10]): rear = 0: private void expandCapacity) { if (rear == array.length) { array = Arrays.copyOf(array, array.length 2): @Override public void add(E element) { / TODO @Override public E…
