String类包含用于连接两个字符串的方法: string1.concat (string2相等); 这将返回一个新的字符串,它是string1,末尾添加了string2。 字符串通常与+运算符连接,如in“Hello”+“world”+“! 需要注意的是:当使用字符串的时候,如果超过行大小,则需要+连接比如如下: AI检测代码解析 String quote = "Now is the...
s.insert(int index,String str);//将参数str指定的字符序列插入到参数index指定的位置 s.reverse();//翻转字符序列 s.delete(int startIndex,int endIndex);//从当前字符序列中删除一个子字符序列(从start到end),并返回当前对象的引用 s.replace(int startIndex,int endIndex,String str);//将从start到end...
Each such collection has a well-defined first element, second element, and so forth, up to the last element. Provides uniform APIs for accessing its first and last elements, and for processing its elements in reverse order. Value: Improves developer productivity by offering a uniform set of ...

It is a string that is not likely to happen in the stack trace of some other application, and at the same time, there is only a tiny chance that it disappears from later IntelliJ versions. It is also to note that creating the stack trace this way is time-consuming. When the code ...
