What is an easy way to create an exception handling class in Java?

You are about to create an exception handling class.

public class MyException extends Exception {}

public class Foo {
  public bar() throws MyException {
    throw new MyException("try again please");
  }
}

I tried it like this. In the compiler, cannot find symbol: constructor MyException(java.lang.String) There's an error like this. But isn't the constructor inherited from java.lang.Exception?

The constructor must be newly defined. And you have to call super (message) in the constructor to include the parent constructor. For example,

public class MyException extends Exception {
    public MyException(String message) {
        super(message);
    }
}

You have to do it like this.
