How to propagate an exception in java

Question

I am a C programmer and just learning some java recently because I am developing one android application. Currently I am in a situation. Following is the one.

Answer 1

Don't catch it and rethrow again. Just do this and catch it in the place you want

public void myMethod() throws ExceptionType1, ExceptionType2 {
    // other code
}

Example

public void someMethod() {
    try {
        myMethod();
    } catch (ExceptionType1 ex) {
        // show your dialog
    } catch (ExceptionType2 ex) {
        // show your dialog
    }
}
