Boolean Class

Boolean class wraps value of boolean data type in an object. If we want to pass boolean variable in a method which require object then we need to make Boolean class object then we pass that object.


Constructor:


  Boolean(boolean b) 
or
Boolean(String s)

Boolean class has two type of constructor one take boolean value and another take String representation of boolean value.

Creating Boolean class object


 Boolean b=new Boolean(true);// by using first constructor 
Boolean c=new Boolean("false");// by using second constructor

boolean booleanValue() Returns the value of Boolean this object in form of primitive data type boolean.
int compareTo(Boolean c) Compare two Boolean object numerically.
boolean equals(Object ob) Compare this object against specified object.
