Declaration and initialisation of boolean type.
Non-convertibility of boolean type to other types.

Run Output

true

true

Code Understanding

boolean b=true;
Here we declare boolean data type b which is assigned a true status. true in java is just a reserved word to be used as boolean literal. The opposite of this is false.

//int x=b;
This line has been commented. If we un-comment this the code will not run as boolean type can not be converted to other type

if(b) System.out.println(b);
The boolean type can be directly checked in if conditions without using any comparison operator.

if(b==true) System.out.println(b);
However the use of comparison operator with boolean type is also allowed.
