This worked for me:<br />
<br />

<pre><code id="code-20-37733448-1">      String stest = &quot;Test-Test2-2.1.2&quot;;

        stest = stest.replaceAll(&quot;-[\\d].*&quot;,&quot;&quot;);

        System.out.println(stest);</code></pre>
<br />
<br />
<br />

<pre><code id="code-20-37733448-2">Test-Test2</code></pre>
</div>


This worked for me:



      String stest = "Test-Test2-2.1.2";

        stest = stest.replaceAll("-[\\d].*","");

        System.out.println(stest);




Test-Test2

Yes, but you don't need the character class<br />
<br />

<pre><code id="code-20-37733488-1">s = s.replaceAll(&quot;-\\d.*&quot;,&quot;&quot;)</code></pre>
</div>


Yes, but you don't need the character class



s = s.replaceAll("-\\d.*","")

Java Regular expression

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.

Programming

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
