If any one knows the solution please help me.

As noted in the comments, the TestNG website says:

Requirements

TestNG Upto v7.5: JDK 8 or higher.

TestNG v7.6.0 and above: JDK 11 or higher.

So the possible solutions are:

1. Use an older version of TestNG than v7.6.0 if you want to use Java 8 as your development platform. The TestNG version will probably be in your project's POM file.

2. Upgrade your development platform to Java 11 or later.

3. If you are feeling brave¹, attempt to backport the version of TestNG (>= v7.6.0) that you are using to run on Java 8 (or older).
