Equivalent of 4gl "RECORD LIKE" statement in Java

Question

In 4gl, the statement DEFINE IO_AFPOPF1 RECORD LIKE AFPOPF1.* means all content of table AFPOPF1 assigned to IO_AFPOPF1 variable. If AFPOPF1 table changes, IO_AFPOPF1 also changes automatically.

Can I do the same function in Java? Now I just define a class that store all the content of table AFPOPF1. If AFPOPF1 changes, I must add or delete fields in my class. For example code below:

public class Afpopf1 {
    private int var1;
    private int var2;

    public Afpopf1(int var1,int var2) { this.var1=var1; this.var2=var2;}
    public int getVar1() { return var1; } 
    public int getVar2() { return var2; }
}
