Further to above a small update, clone will peform shallow
copy.Please execute below example and check the output.

public class CloneExamples {

public static void main(String[] args) {
ArrayList al = new ArrayList();

for(int i = 0; i < 10; i++ )
al.add(new Int(i));

System.out.println("al: " + al);

ArrayList al1 = (ArrayList)al.clone();

// Increment all al1's elements:
for(Iterator e = al1.iterator(); e.hasNext
(); )
((Int)e.next()).increment();

// See if it changed al's elements:
System.out.println("al: " + al);
System.out.println("al1: " + al1);
}
}

class Int {

private int i;

public Int(int ii) { i = ii; }

public void increment() { i++; }

public String toString() {
return Integer.toString(i);
}
}

o/p:
al: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
al: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
al1: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

the old ArrayList and the cloned ArrayList are aliased to
the same objects
