Demonstrate Boolean Values

//demonstrate boolean values.
class BoolTest  {
  public static void main(String args[])  {
     boolean b;
     System.out.println("b is "+b);
     System.out.println("b is "+b);
     //a boolean value can control the if statement
     if(b) System.out.println("this is xecuted");//i.e. if b is true
     if (b)System.out.println("this is not xecuted");
     //outcome of a relational operator is a boolean value
     System.out.println("10 > 9 is " +(10>9));

The output generated by the program is :
  b is false
  b is true
  this is xecuted
  10 > 9 is true
  Normal Termination
  Output completed (4 sec consumed).

Few things to note in the above example :
 When a boolean value is outputted by println () , true or false is displayed .

 The value of a boolean variable is sufficient , by itself ,  to control the if statement .

 The outcome of a relational operator is a boolean value  .

 This is why the expression 10 > 9 displays the value true .
