Maybe you want to use Google Guava:

Code:

import static com.google.common.base.CaseFormat.LOWER_CAMEL;
import static com.google.common.base.CaseFormat.LOWER_UNDERSCORE;

public class Main {
    public static void main(String[] args) {
        String str = "load_id,policy_id,policy_number";
        for(String columnName : str.split(",")) {
            System.out.println(LOWER_UNDERSCORE.to(LOWER_CAMEL, columnName));
        }
    }
}

Output:

loadId
policyId
policyNumber
