Boolean类在Java中的重要性是什么？

<strong>public final class Boolean extends Object implements Serializable, Comparable</strong>

public class BooleanTest {
   public static void main(String[] args) {
      Boolean b;
      b = new Boolean(true);
      boolean b1;
      b1 = b.booleanValue();
      String data = "The Primitive value of Boolean object " + b + " is " + b1;
      System.out.println(data);
   }
}

The Primitive value of Boolean object true is true

public class BooleanTest1 {
   public static void main(String args[]) {
      Boolean b1, b2;
      b1 = new Boolean(true);
      b2 = new Boolean("false");
      System.out.println("b1 Value is : "+ b1.booleanValue());
      System.out.println("b2 Value is : "+ b2.booleanValue());
      System.out.println("b1 compareTo b2 : "+ b1.compareTo(b2));
      System.out.println("b1 equals b2 : "+ b1.equals(b2));
   }
}

b1 Value is : true
b2 Value is : false
b1 compareTo b2 : 1
b1 equals b2 : false
