Answer the given question with a proper explanation and step-by-step solution. Hello team, Need some help with problems below using the langauge JAVA. I need to modify the CalcParser class provided below. I need this to produce a string containing commands to evaluate the expression on a stack machine. For example, if you give the command java CalcParser 1+2*3, the output should be a sequence of stack commands such as this: push 1.0 push 2.0 push 3.0 multiply add 7.0 For the command java CalcParser (1+2)*3, on the other hand, it should print a sequence like this: push 1.0 push 2.0 add push 3.0 multiply 9.0 CODE:public class CalcParser { private CalcLexer lexer; private String errorMessage = null; private double value; public CalcParser(String s) { lexer = new CalcLexer(s);errorMessage = lexer.getErrorMessage();if (errorMessage != null) return; value = parseExpression();if (errorMessage != null) return; match(CalcLexer.EOLN_TOKEN);if (errorMessage != null) return; } public String…
Please solve this problem in Java. It should read the elements of the stack as integers from a text file. n = 18 (number of elements/integers)
IN JAVA Suppose that in the array-based stack, the array doubles in size after multiple push operations. But later on, fewer than half of the array’s locations might actually be used by the stack due to pop operations. Revise the implementation so that its array also can shrink in size as objects are removed from the stack. Accomplishing this task will require two new private methods, as follows: The first new method checks whether we should reduce the size of the array: private boolean isTooBig() This method returns true if the number of entries in the stack is less than half the size of the array and the size of the array is greater than 20. The second new method creates a new array that is three quarters the size of the current array and then copies the objects in the bag to the new array: private void reduceArray() Implement each of these two methods, and then use them in the definition of pop()
Java ProgramI will give an upvote to one that can help me. Instructions:- Create a java program using the concept of PDA (Push Down Automata) - This program will check if the input is a palindrome or a balanced symols. - It must use a stack way- Make it simple as possible Take note: You can copy from google but modify it to satisfy the needs of the student. Thank you so much!
My last question was not answered so I am trying again. Please solve this problem in Java. Please a create Java class that does the Pop() operation on a stack as described in the image below. The class will need to read the integers from the text file and Text file(Stack_Ints.txt): 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Sample Output: Print: stack elements print: Popped element print: updated stack elements
java /* Practice Stacks and ourVector Write a java program that creates a stack of integers. Fill the stack with 30 random numbers between -300 and +300. A)- With the help of one ourVector Object and an additional stack, reorganize the numbers in the stack so that numbers smaller than -100 go to the bottom of the stack, numbers between -100 and +100 in the middle and numbers larger than +100 in the top (order does not matter) B)- (a little harder) Solve the same problem using only one ourVector object for help C)- (harder) Solve the same problem using only one additional stack as a helper */ public class HWStacks { public static void main(String[] args) { // TODO Auto-generated method stub } }
.) The following stack stores a stack of integers. Draw the stacks and determine what is the output of the following program? import java.util.*; public class TestStack1 { public static void main(String ... args) { Stack<Integer> s = new Stack< >( ); s.push(-54); s.push(27); s.push(31); System.out.println(s.pop( )); Integer v = s.pop( )+ s.pop( ) % 3; s.push(v); s.push(21); int w = s.pop( ); int x = s.pop( ); s.push(x % w - v); System.out.println(s.pop( )); Integer a=-2, b=5, c=22, d=4; s.push(a); s.push(b); s.push(c); s.push(d); s.push(s.pop( ) + s.pop( )); s.push(s.pop( ) * s.pop( )); while(!s.empty()) {System.out.println(s.pop( ));} } }
Draw a memory map for the code you see on the next page, until the execution reaches the point indicated by the comment /* HERE */.In your diagram:• You must have a stack, heap, and static memory sections • Identify each frame as illustrated by the previous examples.• Draw your variables as they are encountered during program execution. Code: public class Passenger {private String name;private int ticketCost;private StringBuffer luggage;private static final int LUGGAGE_COST = 20;public Passenger(String name, int ticketCost) {this.name = name;this.ticketCost = ticketCost;luggage = new StringBuffer();}public Passenger addLuggage(String desc) {ticketCost += LUGGAGE_COST;luggage.append(desc);return this;}public int getTicketCost() {return ticketCost;}public Passenger reduceCost(int by) {ticketCost -= by;/* HERE */return this;}public String toString() {return "Passenger [name=" + name + ", ticketCost=" + ticketCost + ", luggage=" + luggage + "]";}}public class Driver {public static void…
What does the following code fragment print when N is 50? Give a high-level description of what it does when presented with a positive integer N. Stack stack = new Stack(); while (N > 0) { stack.push(N % 2); N = N / 2; } for (int d : stack) StdOut.print(d); StdOut.println();
please check the error of my code then do a comment line of my code (Subject: Java Programming): public class StackTest{ static public void main(String... args){ MyStack stack = new MyStackArray(); System.out.print("ENTER AN INTEGER VALUE(n): "); int dec = new java.util.Scanner(System.in).nextInt(); int rem = dec%2; stack.push(rem); dec/=2; while(dec!=0) { int rem = dec%2; stack.push(rem); dec/=2; } System.out.print("Decimal to Binary :"); while(!(stack.isEmpty())){ System.out.print(stack.pop()); }
Can you help me with this question ? Show what is written by the following segments of code, given that item1, item2, and item3 are intvariables. Assume all methods are available. Stacktype stack;int _tmain(int argc, _TCHAR* argv[]){stacktype stack;int item1, item2, item3;item1 = 9;item3 = -2;item2 = item1 + 1;stack.push(item2);stack.push(item2 + 9);stack.push(item1);item2 = stack.pop();item1 = item2 + 1;stack.push(item1);stack.push(item3);while (!stack.isempty()){item3 = stack.pop();cout << item3 << endl;}cout << " =============================================" << endl;cout << item1 << endl << item2 << endl << item3 << endl;return 0;}
This question involved the use of stack and queue (like u see below) Those are the class definitions for stacks and queues of integers (like u see below) Need the solution of the program step-by-step please!
