Java 使用Scanner（）读取CSV

Question

我的csv正在读入System.out，但是我注意到任何带空格的文本都移到下一行（作为返回\ n）

这是我的csv的启动方式：

first,last,email,address 1, address 2
john,smith,[e-mail],123 St. Street,
Jane,Smith,[e-mail],4455 Roger Cir,apt 2

运行我的应用程序后，任何带有空格（地址1）的单元格都将扔到下一行。

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;

public class main {

    public static void main(String[] args) {
        // -define .csv file in app
        String fileNameDefined = "uploadedcsv/employees.csv";
        // -File class needed to turn stringName to actual file
        File file = new File(fileNameDefined);

        try{
            // -read from filePooped with Scanner class
            Scanner inputStream = new Scanner(file);
            // hashNext() loops line-by-line
            while(inputStream.hasNext()){
                //read single line, put in string
                String data = inputStream.next();
                System.out.println(data + "***");

            }
            // after loop, close scanner
            inputStream.close();


        }catch (FileNotFoundException e){

            e.printStackTrace();
        }

    }
}

因此，这是控制台中的结果：

first,last,email,address 
1,address 
2
john,smith,[e-mail],123 
St. 
Street,
Jane,Smith,[e-mail],4455 
Roger 
Cir,apt 
2

我使用扫描仪的方式有误吗？

Answer 1

scanner.useDelimiter(",");

这应该工作。

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;


public class TestScanner {

    public static void main(String[] args) throws FileNotFoundException {
        Scanner scanner = new Scanner(new File("/Users/pankaj/abc.csv"));
        scanner.useDelimiter(",");
        while(scanner.hasNext()){
            System.out.print(scanner.next()+"|");
        }
        scanner.close();
    }

}

对于CSV文件：

a,b,c d,e
1,2,3 4,5
X,Y,Z A,B

输出为：

a|b|c d|e
1|2|3 4|5
X|Y|Z A|B|
