Here is a link that confirms OriginalGriff's solution.
Java.lang.String.matches() in Java - GeeksforGeeks[^]

Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
RegExr: Learn, Build, & Test RegEx[^]
Online regex tester and debugger: PHP, PCRE, Python, Golang and JavaScript[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx: Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx: Regexper[^]

Solution 1

Try:

Java

public static void main (String[]args)
  {
    String text =
      "This is the text to be searched 45" +
      "for occurrences of the pattern.";
    String pattern = "(.*)searched(.*)";
    boolean matches = Pattern.matches (pattern, text);
    System.out.println ("matches = " + matches);
  }
