For exampleString,Integer, etc. A reifiable type essentially has the same type information at compile-time as it has at run-time. Non-reifiable typesare types where information has been removed at compile-time by type erasure — invocations of generic types that arenot defined as unbounded ...
Literals in Java programming: string, boolean, integer, floating point, and character literals. Java literals are fixed values used in a program. This tutorial covers Java literals in detail.

基本数据类型集合 集合类只能容纳对象句柄。但对一个数组,却既可令其直接容纳基本类型的数据,亦可容纳指向对象的句 柄。利用象 Integer、 Double 之类的“ 封装器”类,可将基本数据类型的值置入一个集合里。 无论将基本类型的数据置入数组,还是将其封装进入位于集合的一个类内,都涉及到执行效率的问题。显 然,若...
If value is a string with spaces, then enclose it in quotation marks (for example -Dfoo="foo bar"). -disableassertions[:[packagename]...|:classname] or -da[:[packagename]...|:classname] Disables assertions. By default, assertions are disabled in all packages and classes. With no ...
