Hi friend,


Code to solve the problem :

import java.util.*;
class ArrayList2
{
public static void main(String[] args)
{
ArrayList al = new ArrayList();
al.add("or");
al.add("c1");
al.add("or");
al.add("c2");
al.add("c3");
al.add("or");
al.add("c4");
System.out.println(al);

String temp = "";

for(int i=0;i<al.size();i++)
{

for(int j=i;j<al.size();j++)
{
if(al.get(i).equals("or"))
{
temp = al.get(i).toString();
al.set(i,al.get(j));
al.set(j,temp);
}

}
}
System.out.println(al);

}
}


Thanks
