Can you name such a legal Java expression? You only need to add brackets to a subexpression to make it an invalid expression, the brackets are added only to indicate the order of values when no brackets are added? Inserting a pair of parentheses to annotate the existing assignment order does not seem to have any impact on the validity of the program. In fact, in

The parentheses in shell have their special usage, which are summarized as follows:1. brackets after the symbol $The value of $ {A} variable A can be omitted without ambiguity.$ (CMD) command is replaced and the result is the output of Shell Command cmd, which has the same effect as 'cmd'. However, some shell versions do not support command replacement in the form of $ (), such as tcsh.$ (Exp) and 'expr exp 'have the same effect. Calculate the number

The sensitive characters in XML are angle brackets, and if the value of XML contains angle brackets, then the parsing will be an error, such as:books>book >ID>1ID>name>three countries play >play >Yiname>price >45price >author>Luo Guan Zhongauthor>book >Books>These XML files need to be processed first.One of my approximate ideas is this:First use the regular to find all the labels, then put the label into a
