String json= ls.get(j).getCwc();
Type type = new TypeToken<List<Example>>(){}.getType();
List<Example> example = new Gson().fromJson(json,type);

where Example is

public class Example {

@SerializedName("company")
@Expose
private String company;
@SerializedName("AvgSal")
@Expose
private String avgSal;

public String getCompany() {
return company;
}

public void setCompany(String company) {
this.company = company;
}

public String getAvgSal() {
return avgSal;
}

public void setAvgSal(String avgSal) {
this.avgSal = avgSal;
}

}

You'll need to create a model class for the object.

Example.java

public class Example{
    String company = "";
    String AvgSal = "";
}

and then you need to write code as below to convert JSONArray string into List<Model>.

String json= ls.get(j).getCwc();
Type modelListType = new TypeToken<ArrayList<Example>>(){}.getType();
ArrayList<Example> modelList = new Gson().fromJson(json, modelListType);

This will convert JSONArray into ArrayList.
