Question

Need help with a Java problem:

Copy the program class provided below called FinalAnswer. This contains only a main method. You are to add your method to that program class. When you compile and run it, the main method will call the method you are writing in response to the problem below.

FinalAnswer.java:

import java.util.ArrayList;
import java.util.Arrays;
import algs13.Stack;
import stdlib.*;

public class FinalAnswer {

   // Your methods go here.

   public static void main(String[] args) {
       StdOut.println(floorlog(32));
       StdOut.println(floorlog(35));
       StdOut.println(floorlog(64));
       StdOut.println(floorlog(2048));

       Double[] sqarray = {3.5, 4.7, 10.1, 25.0, 76.34, 100.01, 256.0};
       ArrayList<Double> dlist = new ArrayList<Double>(Arrays.asList(sqarray));
       StdOut.println(dlist);
       squareRootList(dlist);
       StdOut.println(dlist);

       StdOut.println(falling(10, 2));
       StdOut.println(falling(52, 6));

       dlist = new ArrayList<Double>();
       StdOut.println(sumBelowLimit(dlist, 50.0));
       Double[] sbarray = {45.3, 12.4, 50.1, 32.8, 75.5, 49.9, 50.0};
       dlist = new ArrayList<Double>(Arrays.asList(sbarray));
       StdOut.println(sumBelowLimit(dlist, 50.0));

       ArrayList<Integer> ilist = new ArrayList<Integer>();
       StdOut.println(productOfEvens(ilist));

       Integer[] eparray1 = {2, 3, 4, 9, 11, 12};
       ilist = new ArrayList<Integer>(Arrays.asList(eparray1));
       StdOut.println(productOfEvens(ilist));

       Integer[] eparray2 = {7, 3, 53, 9, 11, 19};
       ilist = new ArrayList<Integer>(Arrays.asList(eparray2));
       StdOut.println(productOfEvens(ilist));

       String[] starray = {"hello", "how", "are", "you"};
       reverse(starray);
       StdOut.println(Arrays.toString(starray));
   }
}

Write a public static method reverse that takes as a parameter an array of strings and, using a stack, reverses the order of the strings in the array

Explanation / Answer

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Stack;
public class FinalAnswer {
// Your methods go here.
public static void reverse(String s[]) {
       Stack<String> stack = new Stack<String>();
       for(int i=0;i<s.length;i++){
           stack.push(s[i]);
       }
       int i=0;
       while (!stack.isEmpty()) {
   String str = stack.peek();
   s[i]=str;
   stack.pop();
   i++;
   }
   }
public static void main(String[] args) {
StdOut.println(floorlog(32));
StdOut.println(floorlog(35));
StdOut.println(floorlog(64));
StdOut.println(floorlog(2048));
Double[] sqarray = {3.5, 4.7, 10.1, 25.0, 76.34, 100.01, 256.0};
ArrayList<Double> dlist = new ArrayList<Double>(Arrays.asList(sqarray));
StdOut.println(dlist);
squareRootList(dlist);
StdOut.println(dlist);
StdOut.println(falling(10, 2));
StdOut.println(falling(52, 6));
dlist = new ArrayList<Double>();
StdOut.println(sumBelowLimit(dlist, 50.0));
Double[] sbarray = {45.3, 12.4, 50.1, 32.8, 75.5, 49.9, 50.0};
dlist = new ArrayList<Double>(Arrays.asList(sbarray));
StdOut.println(sumBelowLimit(dlist, 50.0));
ArrayList<Integer> ilist = new ArrayList<Integer>();
StdOut.println(productOfEvens(ilist));
Integer[] eparray1 = {2, 3, 4, 9, 11, 12};
ilist = new ArrayList<Integer>(Arrays.asList(eparray1));
StdOut.println(productOfEvens(ilist));
Integer[] eparray2 = {7, 3, 53, 9, 11, 19};
ilist = new ArrayList<Integer>(Arrays.asList(eparray2));
StdOut.println(productOfEvens(ilist));
String[] starray = {"hello", "how", "are", "you"};
reverse(starray);
StdOut.println(Arrays.toString(starray));
}
}
