public class ArrayListDeleteParticularDataTypeExample {
/**

public static void main(String[] args) {
ArrayListDeleteParticularDataTypeExample obj = new ArrayListDeleteParticularDataTypeExample();
ArrayList al = new ArrayList();
al.add(new Integer(1));
al.add(new Integer(2));
al.add(new Integer(3));
al.add("A");
al.add("B");
al.add("C");
al.add(new Float(10.10));
al.add(new Float(20.20));
al.add(new Float(30.30));
System.out.println("ArrayList Size Before - "+al.size());
System.out.println("ArrayList Values Before- "+al);
Iterator it = al.iterator();
while(it.hasNext()){
if(it.next() instanceof String){
it.remove();
}
}
System.out.println("ArrayList Size After - "+al.size());
System.out.println("ArrayList Values After - "+al);
