我想使用已提供的 2D 字符串数据数组创建所有者及其属性的数组列表。我不知道如何转换字符串以使它们成为所有者列表。我需要首先检查所有者列表是否为空，如果是，则将所有者名称添加到列表中。
import java.util.ArrayList;
import javax.swing.JOptionPane;
public class PropertyTest {
public static void main(String[] args) {
boolean present = true;
ArrayList <Owner> ownerList = new ArrayList <Owner>();
String dataArray[][] = {{"Jones","Commercial","123 Mitchell","Arlington","Texas","76019","120000", "sales", "21000"},
{"Smith","Residential","61 Bose Lane","Dallas","Texas","75002","310000", "65656"},
{"Jones","Commercial","2500 West Seventh St"," Fort Worth","Texas","76015","575000","food", "15750"},
{"Smith","Commercial","1225 Green Rd","Euless","Texas","76000","215500","entertainment","9500"},
{"Jones","Residential","5214 Linda Lane","Houston","Texas","77700","195775", "98541"}};
最佳答案
此代码将帮助您获得正确的输出。 如果我以这个字符串数组为例:java
public <T> List<T> twoDArrayStringToList(T[][] dataArray) {
List<T> list = new ArrayList<T>();
for (T[] array : dataArray) {
list.addAll(Arrays.asList(array));
}
return list;
}
public static void main(String args[]){
String dataArray[][] = {{"Jones","Commercial","123 Mitchell","Arlington","Texas","76019","120000", "sales", "21000"},
{"Smith","Residential","61 Bose Lane","Dallas","Texas","75002","310000", "65656"},
{"Jones","Commercial","2500 West Seventh St"," Fort Worth","Texas","76015","575000","food", "15750"},
{"Smith","Commercial","1225 Green Rd","Euless","Texas","76000","215500","entertainment","9500"},
{"Jones","Residential","5214 Linda Lane","Houston","Texas","77700","195775", "98541"}};
System.out.println(twoDArrayStringToList(dataArray));
}
