Java – what is the purpose of the original getter / setter in the field?

This is explained in the documentation of the public object get (object obj) method of the field class

And for public void set (object obj, object value)

So I'm right. The only purpose of specific original getters and setters such as getInt and setint is to prevent redundant type conversion? Because this code works correctly

public class Test{  
    int i = 1;
    public static void main(String[] args) throws Exception{
        Test inst = new test();
        Class<?> clazz = inst.getClass();
        Field fi = clazz.getDeclaredField("i");
        int ii = (int) fi.get(inst);
        Integer iii = new Integer(ii * 2);
        fi.set(inst,iii);
    }
}

I ask if anyone knows the scenarios where you need to use these methods, except for performance reasons

Solution

This is for type safety and efficiency Also consider that the – get * () method is the expected way to access the original field, and doing so through get () just works, but requires boxing / unboxing

In other words, the only reason to use get () on the original field is if you don't know its type in advance
