If I got your question right here is solution

try it out

package collection;



import java.util.ArrayList;



public class CollectionTest {



public static void main(String[] args) {



try {



ArrayList oArrayList = new ArrayList();


// Populate the data for application


oArrayList.add("A");oArrayList.add("B");oArrayList.add("C");oArrayList.add("D");oArrayList.add("E");



String strTemp = "";


int iStartIndex = 0;


int iEndIndex = 0;


System.out.println(" : Data --> " + oArrayList.toString());



if(args.length %2 == 0) {


System.out.println("
Valid argument list");


for(int i = 0; i<= args.length/2; i=i+2) {



iStartIndex = Integer.parseInt(args[i]);


iEndIndex = Integer.parseInt(args[i+1]);


//check data is within arraylist else will give error


if(iStartIndex <= oArrayList.size() && iEndIndex <= oArrayList.size()) {


System.out.println("
Valid indexes let's do swapping");


strTemp = oArrayList.get(iStartIndex-1).toString();


oArrayList.remove(iStartIndex-1);


oArrayList.add(iEndIndex-1, strTemp);


System.out.println(" : " + iStartIndex + " moved to " + iEndIndex + " --> " + oArrayList.toString());


} else {


System.out.println("
Invalid index specified");


} // End of if loop


}// End of for loop


} else {


System.out.println("
InValid argument list");


} // End of if loop


} catch (Exception ex) {


System.out.println(" Exception occured at runtime : " + ex.getMessage());


}


} // End of main


}// End of class
