public static void main(String args[]) {
ArrayList<String> list = new ArrayList<String>();
list.add("2");
list.add("3");
list.add("4");
list.add("5");
System.out.println("size :"+list.size());
for(int i=0;i<list.size();i++) {
list.remove(i);

Write down program for following scenario. Use java coding
standard.
You have array list with some words in it..we will call it
as dictionary….and you have a arbitrary string containing
some chars in it.
You have to go through each word of dictionary and find out
if that word can be constructed with the help of chars from
arbitrary string given. If you find the word print it else
print none.
if we have a column (Key) in a table.
and values of that column is
Key
1
1
1
2
2
3
3
4
4
5
5
5
and we want to show the data after query..like..
1(3)
2(3)
3(2)
4(2)
5(3)
how many times a single term comes..
