特征选择 —— 也叫特征子集选择（FSS，Feature Subset Selection）。是指从已有的 M 个特征（Feature）中选择 N 个特征使得系统的特定指标最优化，是从原始特征中选择出一些最有效特征以降低数据集维度的过程，是提高算法性能的一个重要手段，也是模式识别中关键的数据预处理步骤。
Java 语言是简单的： Java 语言的语法与 C 语言和 C++ 语言很接近，使得大多数程序员很容易学习和使用。另一方面，Java 丢弃了 C++ 中很少使用的、很难理解的、令人迷惑的那些特性，如操作符重载、多继承、自动的强制类型转换。特别地，Java 语言不使用指针，而是引用。并提供了自动分配和回收内存空间，使得程序员不必为内存管理而担忧。
final 变量：final 表示”最后的、最终的”含义，变量一旦赋值后，不能被重新赋值。被 final 修饰的实例变量必须显式指定初始值。final 修饰符通常和 static 修饰符一起使用来创建类常量。 final 方法：父类中的 final 方法可以被子类继承，但是不能被子类重写。声明 final 方法的主要目的是防止该方法的内容被修改。 final 类：final 类不能被继承，没有类能够继承 final 类的任何特性。
abstract 修饰符
抽象类：抽象类不能用来实例化对象，声明抽象类的唯一目的是为了将来对该类进行扩充。 一个类不能同时被 abstract 和 final 修饰。如果一个类包含抽象方法，那么该类一定要声明为抽象类，否则将出现编译错误。 抽象类可以包含抽象方法和非抽象方法。 抽象方法：抽象方法是一种没有任何实现的方法，该方法的具体实现由子类提供。

Java switch case 语句
查看Java switch case 语句
+
+
Java 中switch case语句与 C 语言完全相同，故只做简单示例。
switch case的语法格式如下
1 2 3 4 5 6 7 8 9 10 11
switch(expression){
+case value :
+//语句
+break;//可选
+case value :
+//语句
+break;//可选
+//你可以有任意数量的case语句
+default://可选
+//语句
+}
switch 语句中的变量类型可以是byte,short,int,char。从 Java SE 7 开始，支持字符串String类型，同时case标签必须是字符串常量或字面量。
InputStream f =newFileInputStream("C:/java/hello");
+
+File f =newFile("C:/java/hello");
+InputStream in =newFileInputStream(f);
+
+OutputStream f =newFileOutputStream("C:/java/hello")
+
+File f =newFile("C:/java/hello");
+OutputStream fOut =newFileOutputStream(f);
上面两种写法，虽然属性 p 的读取和赋值行为是一样的，但是有一些细微的区别。第一种写法，属性 p 的 configurable 和 enumerable 都为 false，从而导致属性 p 是不可遍历的；第二种写法，属性 p 的 configurable 和 enumerable 都为 true，因此属性 p 是可遍历的。实际开发中，写法二更常用。
// Select the node that will be observed for mutations
+consttargetNode=document.getElementById("some-id");
+
+// Options for the observer (which mutations to observe)
+constconfig= { attributes: true, childList: true, subtree: true };
+
+// Callback function to execute when mutations are observed
+constcallback= (mutationList, observer) => {
+for (constmutationofmutationList) {
+if (mutation.type==="childList") {
+console.log("A child node has been added or removed.");
+ } elseif (mutation.type==="attributes") {
+console.log(`The ${mutation.attributeName} attribute was modified.`);
+ }
+ }
+};
+
+// Create an observer instance linked to the callback function
+constobserver=newMutationObserver(callback);
+
+// Start observing the target node for configured mutations
+observer.observe(targetNode, config);
+
+// Later, you can stop observing
+observer.disconnect();
+
+// 保存所有没有被观察器处理的变动
+varchanges=mutationObserver.takeRecords();
+
+// 停止观察
+mutationObserver.disconnect();
popstate 事件在浏览器的 history 对象的当前记录发生显式切换时触发。注意，调用 history.pushState()或 history.replaceState()，并不会触发 popstate 事件。该事件只在用户在 history 记录之间显式切换时触发，比如鼠标点击“后退/前进”按钮，或者在脚本中调用 history.back()、history.forward()、history.go()时触发。 该事件对象有一个 state 属性，保存 history.pushState 方法和 history.replaceState 方法为当前记录添加的 state 对象。
let与const都不会发生变量提升，并且都是块级作用域 这是因为 var 和 let/const 在变量声明时有不同的机制。var 声明的变量会发生变量提升，也就是说，它们的声明会被提升到作用域的顶部，但是赋值操作不会被提升。所以在声明之前使用 var 变量，不会报错，但是变量的值是 undefined，而不是赋值后的值。例如：
TranslucentTB 在 2022 年 12 月的一次更新中添加了中文版本，并解决了之前版本任务栏透明顶部仍有一条细线的问题(之前此问题可配合RoundedTB解决)，现阶段 TranslucentTB 支持中文并且可独立实现 Windows 任务栏透明美化

constre= /(\w+)\s(\w+)/;
+conststr="Maria Cruz";

+"The quick brown fox jumps over the lazy dog. If the dog reacted, was it really lazy?";
+
+console.log(p.replace("dog", "monkey"));
+// Expected output: "The quick brown fox jumps over the lazy monkey. If the dog reacted, was it really lazy?"
+
+constregex= /Dog/i;
+console.log(p.replace(regex, "ferret"));
+// Expected output: "The quick brown fox jumps over the lazy ferret. If the dog reacted, was it really lazy?"
+// 函数调用的情况
+functionreplacer(match, p1, p2, p3, offset, string) {
+// p1 is non-digits, p2 digits, and p3 non-alphanumerics
+return [p1, p2, p3].join(" - ");
+}
+constnewString="abc12345#$*%".replace(/([^\d]*)(\d*)([^\w]*)/, replacer);
+console.log(newString); // abc - 12345 - #$*%
+
+
replaceAll：配置属性与replace基本相同，相当于replace的全局配置版本。
+
使用字符串作为pattern和使用Regex对象作为pattern行为上有些区别
+
+
1 2 3 4 5 6 7 8 9 10 11 12
functionunsafeRedactName(text, name) {
+returntext.replace(newRegExp(name, "g"), "[REDACTED]");
+}
+functionsafeRedactName(text, name) {
+returntext.replaceAll(name, "[REDACTED]");
+}
+
+constreport=
+"A hacker called ha.*er used special characters in their name to breach the system.";
+
+console.log(unsafeRedactName(report, "ha.*er")); // "A [REDACTED]s in their name to breach the system."
+console.log(safeRedactName(report, "ha.*er")); // "A hacker called [REDACTED] used special characters in their name to breach the system."
+
+
search：search() 方法用于在 String 对象中执行正则表达式的搜索，寻找匹配项。
+
如果匹配成功，则返回正则表达式在字符串中首次匹配的索引；否则，返回 -1。
+
+
1 2 3 4 5 6 7 8 9 10 11
constparagraph=
+"The quick brown fox jumps over the lazy dog. If the dog barked, was it really lazy?";
+
+// Any character that is not a word character or whitespace
+constregex= /[^\w\s]/g;
+
+console.log(paragraph.search(regex));
+// Expected output: 43
+
+console.log(paragraph[paragraph.search(regex)]);
+// Expected output: "."
http(HyperText Transfer Protocol)，即超文本运输协议，是实现网络通信的一种规范。其传输的数据并不是计算机底层上的二进制包，而是完整的，有意义的数据，如HTML文件，图片文件，查询结果等超文本。能够被上层应用识别到。在实际的应用当中，http协议常用于Web浏览器与网站服务器之间传递消息，以明文方式发送内容，不提供任何方式的数据加密。
