Write a method called swapPairs that switches the order of values in an ArrayList of strings in a pairwise fashion. Your method
arsen [322]

Answer:

  1. import java.util.ArrayList;
  2. public class Main {
  3.    public static void main(String[] args) {
  4.        ArrayList<String> strList =new ArrayList<String>();
  5.        strList.add("to");
  6.        strList.add("be");
  7.        strList.add("or");
  8.        strList.add("not");
  9.        strList.add("to");
  10.        strList.add("be");
  11.        strList.add("hamlet");
  12.        swapPairs(strList);
  13.        System.out.println(strList);
  14.    }
  15.    public static void swapPairs(ArrayList<String> list){
  16.        for(int i=0; i < list.size()-1; i+=2){
  17.            String temp = list.get(i);
  18.            list.set(i, list.get(i+1));
  19.            list.set(i+1, temp);
  20.        }
  21.    }
  22. }

Explanation:

Firstly, let's create a method swapPairs that take one ArrayList (Line 18). In the method, use a for-loop to traverse through each item in the ArrayList and swap the items between the current items at index-i and at index-i+1 (Line 19-22). The index-i is incremented by two in next loop and therefore the next swapping will proceed with third and fourth items and so forth.

In the main program, create a sample ArrayList (Line 5-12) and then test the method (Line 14) and print the output (Line 15). We shall get  [be, to, not, or, be, to, hamlet].

class BaseballPlayer {

 private int atBats;

 private String name;

 public BaseballPlayer(String n,int h,int a) {

   name=n;

   hits=h;

   atBats=a;

 }

 public void printBattingAverage() {

   double battingAverage = hits / (double)atBats;

   System.out.println(battingAverage);

 }

 public String toString() {

   return name + ": "+hits+"/"+atBats;

 }

}

public class Baseballtester{

 public static void main(String[] args){

   BaseballPlayer babeRuth = new BaseballPlayer("Babe Ruth", 2873, 8399);

   System.out.println(babeRuth);

   babeRuth.printBattlingAverage();

 }

}

Explanation:

The BaseballPlayer class is used to get and hold data of an instance of a baseball player. the instance object holds the name, number of hits and bats of the player.

The constructor is used to initialize the name, hits and atBats variables of an instance. The "printBattlingAverage" method returns the ratio of the hits and atBat variable while the string method "toString" returns the name and the hits to atBats ratio in string format.
