TRUE is a reference to an object of the class Boolean, while true is just a value of the primitive boolean type. Classes like Boolean are often called “wrapper classes”, and are used when you need an object instead of a primitive type (for example, if you’re storing it in a data structure).

What’s the difference between Boolean and Boolean in Java?

In Java, a boolean is a literal true or false, while Boolean is an object wrapper for a boolean. There is seldom a reason to use a Boolean over a boolean except in cases when an object reference is required, such as in a List.
