如何使用Java将数组的内容存储在文件中?
您可以使用Writer类将数据写入文件。在下面给出的示例中,我们使用BufferedWriter编写数组的内容。
示例
import java.io.BufferedWriter;import java.io.FileWriter;
public class WritingStringArrayToFile {
public static void main(String args[]) throws Exception {
String[] myArray = {"JavaFX", "HBase", "OpenCV", "Java", "Hadoop", "Neo4j"};
BufferedWriter writer = new BufferedWriter(new FileWriter("myFile.txt", false));
for(int i = 0; i < myArray.length; i++) {
writer.write(myArray[i].toString());
writer.newLine();
}
writer.flush();
System.out.println("Data Entered in to the file successfully");
}
}
输出结果
Data Entered in to the file successfully
如果您验证文件,则可以观察到该文件具有数组的内容-
示例
import java.io.BufferedWriter;import java.io.FileWriter;
public class WritingIntArrayToFile {
public static void main(String args[]) throws Exception {
Integer[] myArray = {23, 93, 56, 92, 39};
BufferedWriter writer = new BufferedWriter(new FileWriter("myFile.txt", false));
for(int i = 0; i < myArray.length; i++) {
writer.write(myArray[i].toString());
writer.newLine();
}
writer.flush();
System.out.println("Data Entered in to the file successfully");
}
}
输出结果
Data Entered in to the file successfully
