Java Read CSV File In Java With OpenCSV library, int filed 属性为 int类型

sample2.csv

COUNTRY,CAPITAL,POPULATION
India,New Delhi, 100
People's republic of China,Beijing, 200
United States,Washington D.C., 300

Country2.java 中 population 为int类型:

package com.jiangge.csv.opencsvtest;

public class Country2 {
	private String countryName;
	private String capital;
	private int population;
	
	public String getCountryName() {
		return countryName;
	}
	public void setCountryName(String countryName) {
		this.countryName = countryName;
	}
	public String getCapital() {
		return capital;
	}
	public void setCapital(String capital) {
		this.capital = capital;
	}
	
	public int getPopulation() {
		return population;
	}
	public void setPopulation(int population) {
		this.population = population;
	}

}
