java – boolean. Isinstance (true) is false?

problem

Class objects of Boolean fields do not recognize other Boolean values as instances

code

public class Test {
    public boolean b;
    public static void main(String[] args) {
        System.out.println(Test.class.getFields()[0].getType().isinstance(true));
    }
}

result

false

Solution

The method is isinstance (object), so

x.isinstance(true)

It's the same

x.isinstance(Boolean.TRUE);

And Boolean Class is not Boolean Class

Note: the primitive has no getClass () method or any method When you can use it as an object, it is boxed
