Serialization Json mixed structure with jackson

Please check the sample json data: 

String INPUT = "{\"a\":[1,2,{\"b\":true},3],\"c\":3}";

I would like to parse that json with jackson ObjectMapper. As you can see "a" is an array holds both integer and object. How can I define that a variable in POJO using anotations? Thanks in advance

You can create pojo like below, since the array holds different objects, pojo will have array list of type Object to accept every type - 

public class JsonInput {

            @JsonProperty("a")
            private List<Object> a = new ArrayList<Object>();
            @JsonProperty("c")
            private Integer c;

            public List<Object> getA() {
                return a;
            }

            public void setA(List<Object> a) {
                this.a = a;
            }

            public Integer getC() {
                return c;
            }

            public void setC(Integer c) {
                this.c = c;
            }
        }

Note: You may not have further control over the objects inside the array of json input to map it to the pojo class until it holds any specific type.
