如何从 Java 字符串的末尾和开头删除特殊字符

Question

lets say i have a string like

String examplestring = "%,.&/)"hello, mynameis, Fatih-Mehmet?And yours.insidedot.2874d3"( )§("

And i would want to extract the core part of

String goalstring = "hello, mynameis, Fatih-Mehmet?And yours.insidedot 2874d3"

So keeping all special characters within the core but removing all special characters from the end and from the beginning of the string, how could I achieve that?

Thanks in Advance

Answer 1

Assuming you want to extract a single double quoted term from inside the string, surrounded by other possible content at the start or end, we could phrase your requirement as:

String examplestring = "%,.&/)\"hello, mynameis, Fatih-Mehmet!And yours?insidedot.2874d3\"(.)§(";
examplestring = examplestring.replaceAll("^[^\"]*\"|\"[^\"]*$", "");
System.out.println(examplestring);

// hello, mynameis, Fatih-Mehmet!And yours?insidedot.2874d3
