java - 如何避免java中半重复的方法组？

Question

假设我编写了以下方法:

public void submitForm1() {
        open();
        setField(1, "blah");
        setField(3, "bla");
        setField(4, "blah blah");
        submit();
    }

public void submitForm2() {
        open();
        setField(1, "blah");
        checkBox(1 , true);
        submit();
}

....

public void submitForm100() {
        open();
        setField(1, "bla");
        setField(2, "bla bla");
        setField(3, "blah");
        setArea(1, "blah blah");
        submit();
}

这些方法让我感觉自己在不断重复自己。我觉得应该这样写:

public void submitForm1() {
        MyMethods.submitForm(
            {SET_FIELD, 1, "blah"},
            {SET_FIELD, 3, "bla"},
            {SET_FIELD, 4, "blah blah"}
        );
    }

public void submitForm2() {
        MyMethods.submitForm(
            {SET_FIELD, 1, "blah"},
            {CHECKBOX, 1, true}
        );
}

....

public void submitForm100() {
        MyMethods.submitForm(
            {SET_FIELD, 1, "bla"},
            {SET_FIELD, 2, "bla bla"},
            {SET_FIELD, 3, "blah"},
            {SET_AREA, 1, "blah blah"},
        );
}

这样我就不必一遍又一遍地重复所有这些打开和提交方法。

有办法做到这一点吗？

例如，您可以使用“回调”。为此，请执行以下操作:

void doInSubmit(SubmitCallback callback)
{
    open();
    callback.call();
    submit();
}

外面:

public void submitForm100() 
{
    doInSubmit(new SubmitCallback() 
    {
        void call()
        {
            setField(1, "bla");
            setField(2, "bla bla");
            setField(3, "blah");
            setArea(1, "blah blah");
        }
    })        
}
