问题 I have installed the "WebSphere Application Server Developer Tools for Eclipse V8.5.1" as well as "WebSphere Application Server for Developers V8.5" from here: https://www.ibm.com/developerworks/mydeveloperworks/blogs/wasdev/entry/download?lang=en. I am using Eclipse Juno. I used the First Steps tool to create a profile for application development. I added a "WebSphere Application Server v8.5" server to the Server view, pointing it at that profile. When I right click on the Server in the

Lightweight Java Decimal Class

由 生来就可爱ヽ(ⅴ＜●) 提交于 2021-02-18 20:27:31
问题 I am considering writing two limited precision alternatives to BigDecimal, namely DecimalInt and DecimalLong. These would be capable of dealing with numbers within the real bounds of int and long with an arbitrary number of decimal places, creatable in both mutable and immutable form. My plan is to make DecimalInt support +/-999,999,999 to +/- 0.999999999 and DecimalLong the same, but with up to 18 digits. This would be done by maintaining a decimal digit count value of 0-9 for DecimalInt and

Oracle与Sql server的区别 来源 https://www.cnblogs.com/fengxiaojiu/archive/2017/11/16/7844994.html 一直搞不明白Oracle数据库和sql server的区别，今天我特意查资料把他们的区别整理出来 Oracle数据库：Oracle Database，又名Oracle RDBMS，或简称Oracle。是 甲骨文公司 的一款 关系数据库管理系统 。 它是在数据库领域一直处于领先地位的产品。可以说Oracle数据库系统是目前世界上流行的关系数据库管理系统，系统可移植性好、使用方便、功能强，适用于各类大、中、小、微机环境。它是一种高效率、可靠性好的 适应高吞吐量的数据库解决方案。 sql server数据库：美国Microsoft公司推出的一种关系型数据库系统。SQL Server是一个可扩展的、高性能的、为分布式客户机/服务器计算所设计的 数据库管理系统 ，实现了与WindowsNT的有机结合，提供了基于 事务 的企业级信息管理系统方案 两者的区别： （1）操作的平台不同 Oracle可在所有主流平台上运行，Oracle数据库采用开放的策略目标，它使得客户可以选择一种最适合他们特定需要的解决方案。客户可以利用很多种第三方应用程序、工具。而SQL Server却只能在Windows上运行了。 　　但SQL

Scale down the Valo theme’s spacing and widget size to that of the Reindeer theme

由 瘦欲@ 提交于 2021-02-18 20:17:24
问题 The new Valo theme is now the default in Vaadin 7.3 apps. This theme renders visually with widgets (buttons, fields, and so on) that are dramatically larger (wider and taller) than in the previous default Reindeer theme. This kind of look is now popular in mobile apps in Android and iOS 7/8 as well as some web sites. But those contexts are for brief usage in the range of mere minutes. In contrast, business-oriented desktop-style apps are used by people for much longer work sessions, perhaps

Jersey rest client not adding query parameters

问题 I'm trying to make a simple jersey rest client for google search api. Client client = ClientBuilder.newClient(); WebTarget target = client.target("https://www.googleapis.com/customsearch/v1"); target.queryParam("q", "mobile"); Response response = target.request().get(); System.out.println(response.readEntity(String.class)); As you've noticed I haven't included key and cx . Don't worry about that, it's just a simple demo. When visiting the url https://www.googleapis.com/customsearch/v1?q

Does BigDecimal#min method qualify as a BinaryOperator?

由 ぃ、小莉子 提交于 2021-02-18 20:11:43
问题 The Stream.reduce method takes a BinaryOperator as an argument. The function signature of a BinaryOperator is (T,T) -> T . The BigDecimal::min method has only 1 parameter in its method signature (ie. (T) -> T ). Why doesn't the compiler complain when I pass BigDecimal::min to the Stream.reduce method? Sample code: List<BigDecimal> bigDecimalList = new ArrayList<>(); bigDecimalList.add(BigDecimal.valueOf(1)); bigDecimalList.add(BigDecimal.valueOf(2)); bigDecimalList.add(BigDecimal.valueOf(3));

Different results when adding same doubles in different order

问题 Why is the output different when adding same numbers? public class Test { public static void main(String a[]) { double[] x = new double[]{3.9, 4.3, 3.6, 1.3, 2.6}; System.out.println(">>>>>>> " + sum(x)); } public static double sum(double[] d) { double sum = 0; for (int i = 0; i < d.length; i++) { sum += d[i]; } return sum; } } Output is : 15.7 and if I interchange values double[] x = new double[] {2.6, 3.9, 4.3, 3.6, 1.3}; I am getting Output as : 15.700000000000001 How do I get the same

Equivalent of TreeSet in Java to C#.net

问题 I have Java code containing a TreeSet . I want to convert the code to C#. Which equivalent collection can I use? If there is none please suggest alternatives. 回答1: I think there is no treeset in C#.

It does have the methods and complexity guarantees that one would
