Wrap your Exception as a RuntimeException when it is not of your method's business

A method is not required to declare in its throws clause any subclasses of RuntimeException that might be thrown during the execution of the method but not caught.

package exceptions;

public class RuntimeExceptionTest {

 public class TestException extends Exception {
  
 }
 
 public static void main(String[] args) {
  RuntimeExceptionTest test = new RuntimeExceptionTest();
  try {
   test.throwWrappedTestExceptionAsRuntimeException();
  } catch (Exception e) {
   System.out.println("exception catched:\n");
   e.printStackTrace();
  }
 }

 private void throwTestException() throws TestException {
  throw new TestException();
 }
 
 
 public void throwWrappedTestExceptionAsRuntimeException() {
  try {
   throwTestException();
  } catch (TestException e) {
   throw new RuntimeException(e);
  }
 }
}
