The primitive data types in Java are byte, short, int, long, float, double, boolean, and char. They are built into the language, and have a value, but no methods.

'a' with single quotes is a char, which is a primitive type. "a" with double quotes is a String, which is not a primitive type.

Primitive data types are not objects. You can't call methods directly on them: 'a'.toString() will give the error char cannot be dereferenced. "a".toString() returns "a".

Two primitive types with the same value will be equal with the == operator: 'a' == 'a' is true, but new String("a") == new String("a") is false, and new String("a").equals(new String("a")) is true.
