How to exit void function in Android?

Question

Hope the system can exit the void function HandlePostwhen condition 1 is encountered, so I add returnafter DoSomething1().

But Android Studio will tell me that the "return" information is redundant as the last statement in the "void" method!

private void HandlePost(IHTTPSession session){
    try {

        Map<String, String> files = new HashMap<String, String>();
        session.parseBody(files);

        //Case 1
        String deleteValue=session.getParms().get("ActionDelete");
        if (deleteValue!=null){
           DoSomething1();
           return;
        }

        //Case 2
        String copyValue=session.getParms().get("ActionCopy");
        if (copyValue!=null){
           DoSomething2();
            return;
        }

    } catch (Exception e) {
        Utility.LogError("This is an error "+e.getMessage() );
    }
}
