NullPointerException when Creating an Array of objects [duplicate]

Answer 1

first of all you have created 5 element of ResultList type, but when inserting value you are inserting name and value wrong. you could use constructor to create and insert values to the array elements.

class ResultList {
    public String name;
    public Object value;
    public ResultList(String name,Object value){
        this.name = name;
        this.value = value;
        System.out.println(name+" --- "+value);
    }
}
public static void main(String[] args) {
        ResultList[] boll = new ResultList[5];
        boll[0] = new ResultList("myName","myValue");
    }
