import java.util.ArrayList;
import java.util.List;

public class BooleanAutoBox {

   @param args
  public static void main(String[] args) {
    boolean bool = false
    List<Boolean> boolList = new ArrayList<Boolean>();
    boolList.add(bool);    //Auto boxing to a Boolean object
    boolList.add(true);    //Auto boxing to a Boolean object  
    Boolean bool2 = new Boolean("true");
    if (bool2) {       //Auto un-boxing to a boolean primitive
      System.out.println("bool is true");


It gives the following output,
[false, true]
bool is true
