Is a boolean primitive in java a type in its own right or can it be manipulated as an int? In other languages I have seen, boolean types can be manipulated as if false=0 and true=1 which can sometimes be quite convenient.

Boolean Class Object. Using the method booleanObjectMethodToInt, we can convert a boolean value to an integer the same way we did with the static method.
The compare() method of Java Boolean class compares the two Boolean values (x and y) and returns an integer value based on the result of this method.
Field setBoolean() method in Java with Examples When you need to set the value of a field of an object as boolean then you can use this method to set value over an Object.
Everything is passed by value. You're not passing an object by reference in Java, you're passing an object reference by value. Boolean b does not hold a Boolean object, it holds a reference (a pointer) to a Boolean object. Second, Boolean (like the other wrapper objects and also String ) are immutable objects.
Is a boolean primitive in java a type in its own right?
Yes. boolean is a primitive type in its own right
can it be manipulated as an int?
No. It can not be implicitly or explicitly cast or otherwise used as an int (Java ain't C)
If you wanted to "coerce" it to an int:
boolean b;
int i = b ? 1 : 0; // or whatever int values you care to use for true/false
