Java 使用FileWriter输出数据到文件

import java.io.FileWriter;
import java.io.IOException;

public class FileWriterCls {
    public static void main(String[] args) {
        Write01();
    }
    public static void Write01(){
        String filePath = "/Users/chen/Files/note.txt";
        //创建FileWriter对象
        FileWriter fileWriter = null;
        char[] chars = {'a','b','c'};
        try {
            fileWriter = new FileWriter(filePath);
            //一、写单个字符
            fileWriter.write('H');
            //二、写数组
            fileWriter.write(chars);
            //三、写入整个字符串
            fileWriter.write(" 红红火火恍恍惚惚～  ");
            //四、写入指定字符串的指定部分
            fileWriter.write(" 渔舟唱晚，响穷彭蠡之滨",5,6);
            //五、写入指定数组的指定部分
            fileWriter.write("我是大傻逼".toCharArray(),2,3);
        } catch (IOException e) {
            e.printStackTrace();
        }finally {
            try {
                fileWriter.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
