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].

A program that contains the following method: public static void display(int arg1, double arg2, char arg3) { System.out.println(
Oduvanchick [21]

Answer:

The method can be accessible from main method of any class.

Explanation:

Main method is the entry point of a program, which means when you start you program the first thing to execute is the main method.

public static void main(String[] args){

// Your code here

}

In the given display method you have int, double and char data types as a arguments. So in order to call display method you need to understand the datatype that you want to pass.

int only takes integers without decimal points.

double take numbers with decimal points.

and char only tak one character

so in order to call display method we need to pass those arguments in right order.

Below is the main method which will call the display method in a right way

public static void main(String[]args){

  display(25,50000.00,'T');

}

Output

The values are 25, 50000.0, and T
