Strong reference is very common in our daily code, for example Object obj = new Object(); Employee emp = new Employe (EmployeeName, EmployeeAge); As long as Strong Reference exists, the garbage collector will no
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 ...

Applications can access a keystore via an implementation of the KeyStore class, which is in the java.security package. The recommended keystore type (format) is "pkcs12", which is based on the RSA PKCS12 Personal Information Exchange Syntax Standard. The default keystore type is "jks", ...
原因分析:Java在编译时,首先会根据实参的数量和类型(这里是2个实参,都为int类型,注意没有转成int数组)来进行处理,也就是查找到calPrice(int price,int discount)方法,而且确认它是否符合方法签名条件。现在的问题是编译器为什么会首先根据2个int类型的实参而不是1个int类型、1个int数组类型的实参来查找方法呢?这...

TypeScript 编译性能优化:Project Reference TypeScript给 JavaScript 添加了一套类型系统,可以在编译期间检查出类型错误,这增加了代码的健壮性,但也多了一个编译的过程。 ts 编译速度与项目规模有关,如果项目比较大,代码很多,那就需要编译很长一段时间。
