Doubt about Try-Catch nested in Java

This is a little doubt about the logic of having a Try-Catch inside another Try-Catch in Java, for example it would have something like this:

try{
 //codigo aqui
   try{
     //Aqui ocurre el error
   }catch(Exception ex){
     System.out.print(ex.getMessage() + "inner exception"); //Entra en este catch
   }

}catch(Exception ex){
  System.out.print(ex.getMessage() + "outer exception");
}

As you can see, I put the internal Try-Catch where I think it will give the error, in the Try of the main Try-Catch, my doubt would be, if it happens to give an error in the internal Try-Catch, it would only print the message of the Internal Catch? Or would the external Catch message also be printed? Or would the two be printed?

Only the "Inner exception" message would be printed, since the exception is only within that catch. If you want to make "jump" to the catch outside you have to make a throw, something like this:

try{
 //codigo aqui
   try{
     //Aqui ocurre el error
   }catch(Exception ex){
     System.out.print(ex.getMessage() + "inner exception"); //Entra en este catch
     throw ex;
   }

}catch(Exception ex){
  System.out.print(ex.getMessage() + "outer exception");
}

Good luck!
