Java程序将字符串数组写入文件
这是我们的文件-
FileWriter writer = new FileWriter("E:/demo.txt");现在，考虑一个字符串数组-
String arr[] = { "ONE", "TWO", "THREE", "FOUR", "FIVE", "SIX", "SEVEN", "EIGHT", "NINE" };将上面的数组写入文件“demo.txt”-
int len = arr.length;
for (int i = 0; i < len; i++) {
writer.write(arr[i] + "-");
}以下是一个示例。在这里，我们的文件是“E：/demo.txt”-
示例
import java.io.FileWriter;
public class Demo {
public static void main(String[] argv) throws Exception {
FileWriter writer = new FileWriter("E:/demo.txt");
String arr[] = { "ONE", "TWO", "THREE", "FOUR", "FIVE", "SIX", "SEVEN", "EIGHT", "NINE" };
int len = arr.length;
for (int i = 0; i < len; i++) {
writer.write(arr[i] + "-");
}
writer.close();
}
}输出如下，即文件中的文本为-
输出结果
ONE-TWO-THREE-FOUR-FIVE-SIX-SEVEN-EIGHT-NINE-
