如何将两个返回类型不同但主体相同的方法与 throw 语句结合起来？

Question

I have two methods with different data types, but with same body. I'm not using any return . I'm using these methods for throwing exceptions only. Is there any way to combine these two methods or any way to optimize the code?

public MyDataType1 method1(MyArg arg){
    /* some logic */
    throw new CustomException();
}
public MyDataType2 method2(MyArg arg){
    /* some logic, same as above method logic*/
    throw new CustomException();
}

PS: I don't want to use interface or some new method with common logic.

Answer 1

Use an interface to make compatible

interface DataType{
}

class MyDataType1 implements DataType{
}

class MyDataType2 implements DataType{
}

You'll be able to

public DataType method1(MyArg arg){
    /* some logic */
    throw new CustomException();
}

Answer 2

It is a little-known language feature called a 'method' :)

public MyDataType1 method1(MyArg arg){
    logic();
    throw new CustomException();
}

public MyDataType2 method2(MyArg arg){
    logic();
    throw new CustomException();
}

private void logic() {
    /* some logic */
}
