在Java中,可以使用FileWriter或者BufferedWriter类将字符串写入文件。下面是一个示例代码:
import java.io.FileWriter; import java.io.BufferedWriter; import java.io.IOException; public class WriteToFile { public static void main(String[] args) { String content = "Hello, World!"; try { FileWriter fileWriter = new FileWriter("output.txt"); BufferedWriter bufferedWriter = new BufferedWriter(fileWriter); bufferedWriter.write(content); bufferedWriter.close(); fileWriter.close(); System.out.println("String has been written to file."); } catch (IOException e) { e.printStackTrace(); } } }
在这个例子中,首先创建一个名为output.txt
的文本文件,然后使用FileWriter和BufferedWriter将字符串"Hello, World!"写入文件中。最后关闭BufferedWriter和FileWriter。
