Solution 3 involves escaping the backslash characters within the registry path string. The backslash character holds significance in strings as it is used to introduce escape characters. On the other hand, Solution 1 addresses the fact that specific characters have special meaning within a Java String...
The backslash\is an escape character in Java Strings. That means backslash has a predefined meaning in Java. You have to use double backslash\\to define a single backslash. If you want to define\w, then you must be using\\win your regex. If you want to use backslash as a literal, yo...

When you have the regex the way you want it, you can paste it into your Java program. You’ll need to escape (backslash) any characters that are treated specially by both the Java compiler and the Java regex package, such as the backslash itself, double quotes, and others (see the ...

In Perl, \1 through \9 are always interpreted as back references; a backslash-escaped number greater than 9 is treated as a back reference if at least that many subexpressions exist, otherwise it is interpreted, if possible, as an octal escape. In this class octal escapes must always begin...

For example, in place of ‘\w,’ we have used ‘\\w.’ Here, extra backslash ‘\’ denotes that the \w is an escape sequence. Alternatively, regex in java can be also used in the following way: import java.util.regex.Pattern;import java.util.regex.MatchResult;import java.util.regex...
