解析CSV拉取数据并进行比较，但不起作用。JAVA

我有一个我创建的CSV文件。我正在尝试提取数据，然后对某些数据进行检查

CSV文件内容

"12/05/14","Hay Square","10.00","10","","",""
"12/05/14","Hay Round","75","1","","",""
"12/05/14","Feed","12.50","10","","",""
"12/05/14","Feet","10","","trusty","",""
"12/05/14","Feed","4","5","","",""
"12/05/14","Wormer","12.75","","trusty","",""
"12/05/14","Feed","12","10","","",""
"","Feed","","","","",""
"12/05/14","Medicine","124.85","","sunny","",""
"12/05/14","Feet","90","","speedy","",""

我使用的是基本代码，打印可以很好地打印它找到的内容，但它不会通过if语句进行比较。我到处找，什么也没找到。奇怪，因为我认为这是普遍的做法

正如您在代码中看到的，我只是在寻找“提要”，并希望打印找到的内容。这只是一个更大项目的测试代码，所以这是非常未完成的

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.Arrays;

public class ReadCSV {

  public static void main(String[] args) {

    ReadCSV obj = new ReadCSV();
    obj.run();

  }

  public void run() {

    String csvFile = "c:/horse/horsespending.csv";
    BufferedReader br = null;
    String line = "";
    String cvsSplitBy = ",";

    try {

        br = new BufferedReader(new FileReader(csvFile));
        while ((line = br.readLine()) != null) {

                // use comma as separator
            String[] country = line.split(cvsSplitBy);
            String test = country[1].toString();
            String tester = "\"Feed\"";
            System.out.println("check " + country[1]);
            if(test == tester){
            System.out.println("found");            
            } 
        }

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (br != null) {
            try {
                br.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    System.out.println("Done");
  }

        }

输出：

check "Purchase"
check "Hay Square"
check "Hay Round"
check "Feed"
check "Feet"
check "Feed"
check "Wormer"
check "Feed"
check "Feed"
check "Medicine"
check "Feet"
Done

您不会将java中的字符串与

==

进行比较，而是使用：

test.equals(tester)

---

因为字符串是java中的对象类型，所以使用.equals（）而不是== 你在考虑原语

testString.equals(toCompareToString) //boolean return

快乐编码！

哦，太粗糙了！我读过这篇文章，但并不认为这是我需要做的。谢谢同上。我读过，但出于某种原因，我认为这不适合我的情况！还在学习，在这里自学直到大学开始。谢谢你的链接！福斯特！！！很高兴我能帮上忙。同舟共济，学以致用，朋友们，继续前进！
