java代码如何将字符串写入文件中呢?

字符串写入到文件中的实现思路

方式1:
   借助FileWriter对象可将字符串写入到文件中

方式2:
   借助BufferedWriter可将字符串写入到文件中

FileWriter示例

try {
    FileWriter writer = new FileWriter("文件路径");
    writer.write("字符串内容");
    writer.close();
} catch (IOException e) {
    e.printStackTrace();
}

BufferedWriter将字符串写入到文件中

try {
    BufferedWriter writer = new BufferedWriter(new FileWriter("文件路径"));
    writer.write("字符串内容");
    writer.close();
} catch (IOException e) {
    e.printStackTrace();
}
