this have far

public class config {     @jsonmerge     public ab[] loc; }  @jsoninclude(jsoninclude.include.non_null) public class ab {     public integer a;     public integer b;      protected ab() { }     public ab(int a0, int b0) {         = a0;         b = b0;     } }  objectmapper mapper = new objectmapper();  config = mapper.readvalue(apostoquotes("{'loc':[{'b':3}]}"), config.class); config = mapper.readerforupdating(config).readvalue(apostoquotes("{'loc':[{'a':9}]}"));

the result 

{"loc":[{"b":3},{"a":9}]}
