Question

Vijay 11:30 12:30
Jai 12:30 12:50
Vijay 13:45 14:25
Vijay 17:25 17:50

我希望每行和每个输入都插入到不同的数组或列表中日期应采用相同的格式。

Answer 1

这就是你想要的，

BufferedReader br = new BufferedReader(new FileReader("/path/to/file"));
ArrayList<String[]> list = new ArrayList<>();
String str;
while(null != (str = br.readLine()))
    list.add(str.split(" "));

这将为您提供包含文件数据的String数组列表。

Answer 2

根据您的要求，这根本不是一个好方法。您应该将数据保存为xml格式，如：

data.xml中

<services>
    <service>
        <serviceName>Vijay</serviceName><startTime>11:30</startTime><endTime>12:30</endTime>
    </service>
    <service>
        <serviceName>John</serviceName><startTime>14:30</startTime>16:30<endTime></endTime>
    </service>
    <service>
        <serviceName>John</serviceName><startTime>13:30</startTime><endTime>14:30</endTime>
    </service>
</employees>

应该有DTO类，例如Service.java。您必须反序列化该xml以使用JAXB创建Service类的多个对象。在这种方法中，您可以更轻松地处理数据。

Service.java

package test.com;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="service")
@XmlAccessorType(XmlAccessType.FIELD)
public class Service {

@XmlElement(name="serviceName")
private String serviceName;

@XmlElement(name="startTime")
private String startTime;

@XmlElement(name="endTime")
private String endTime;

public String getServiceName() {
    return serviceName;
}

public void setServiceName(String serviceName) {
    this.serviceName = serviceName;
}

public String getStartTime() {
    return startTime;
}

public void setStartTime(String startTime) {
    this.startTime = startTime;
}

public String getEndTime() {
    return endTime;
}

public void setEndTime(String endTime) {
    this.endTime = endTime;
}
@Override
public String toString() {
    // TODO Auto-generated method stub
    return serviceName + "  "+startTime+ "  "+endTime;
}

}

ServiceList.java

package test.com;

import java.util.ArrayList;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlElementWrapper;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "serviceList")
@XmlAccessorType(XmlAccessType.FIELD)
public class ServiceList {

    @XmlElement(name = "service")
    private ArrayList<Service> serviceList;

    public ArrayList<Service> getServiceList() {
        return serviceList;
    }

    public void setServiceList(ArrayList<Service> serviceList) {
        this.serviceList = serviceList;
    }
}

TestMain.java

public class TestMain  {

public static void main(String[] args) {

    try {
        JAXBContext context = JAXBContext.newInstance(ServiceList.class);
        Unmarshaller m = context.createUnmarshaller();
        ServiceList s = (ServiceList)m.unmarshal(new File("D:/data.xml"));
        System.out.println(s.getServiceList().get(0).getServiceName());
    } catch (JAXBException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}


}
