publicclassCreateString{publicstaticvoidmain(String[] args){// 直接定义字符串Stringstr1="虎老狮";// new 字符串Stringstr2=newString("Java");// 字符数组→字符串char[] arrChar = {'A','n','d','y'};Stringstr3=newString(arrChar);// 字节数组→字符串byte[] arrByte = {97,98};Strings...
String[] stringArray = { "a", "b", "c", "d", "e" }; boolean b = Arrays.asList(stringArray).contains("a");System.out.println(b);// true 1. 2. 先使用Arrays.asList()将Array转换成List,这样就可以用动态链表的contains函数来判断元素是否包含在链表中。

Strings, which are widely used in Java programming, are a sequence of characters. In the Java programming language, strings are objects. The Java platform provides theStringclass to create and manipulate strings. Creating Strings The most direct way to create a string is to write: ...
String str = "Hello";第二种是通过new关键字创建新对象。比如下面这样，String str = new String("...
