学习笔记 - java FileWriter对文本文件的写入

public class FileWriterTest {

public static void main(String[] args) {
// TODO Auto-generated method stub
new FileWriterTest().writerBychar("gfdonx", "d:\\JAVA之路.txt");
}

public void writerBychar(String str,String filePath){
File file = new File(filePath);
FileWriter fw = null;
try {
fw = new FileWriter(file,true);//这个构造方法是表示添加到文件末尾
for (int i = 0; i < str.length(); i++) {
fw.write(str.charAt(i));
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally{
try {
fw.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}
