Java的数据类型分为两类:primitive和reference类型。我们可以从hold数据这个角度来说。primitive类型可以hold数字和布尔数据;reference类型可以hold对象,接口和数组类型的数据的指针。可以想象后一种数据比较复杂,往往是一段数据,不像primitive的数据是比较单纯的数据单元,比如int,float和boolean。 除了数据构成之外,它们在数据...
Java虚拟机可以处理的类型有两种,一种是原始类型(Primitive Types),一种是引用类型(Reference Types). 与之对应,也存在有原始值(Primitive Values)和引用值(Reference Values)两种类型的数值可用于变量赋值、参数传递、方法返回和运算操作。 原始类型与值 Java虚拟机支持的原始数据类型包括数值类型、布尔类型和returnAddres...
Reference types:除了8种primitive types外,都是reference type. When we instantiate an object: When declare a variable of any reference type: 与给变量赋一个primitive type 不同,reference type 相当于给变量创建一个 instruction memory,对应的是该实例的位置(64 bits),而primitive type是给变量创建一个data ...

When using field-level constraints field access strategy is used to access the value to be validated. This means the validation engine directly accesses the instance variable and does not invoke the property accessor method even if such an accessor exists. ...
