Java在File尾部追加数据的两种方法

package cn.com;
import java.io.FileWriter;
import java.io.RandomAccessFile;
//问题描述: 
//在文件的末尾追加内容
//方法1:利用RandomAccessFile类
//1将randomAccessFile模式设置为rw
//2将randomAccessFile移动(seek)到文件末尾
//3追加数据
//4关闭流

//方法2:利用FileWriter类
//1将FileWriter构造方法第二个参数置为true.表示在尾部追加
//2追加数据
//3关闭流
public class FileTest {
	public static void main(String[] args) {
		FileTest fileTest = new FileTest();
		fileTest.addContentFirst("F:\\temp.txt", "test1");
		fileTest.addContentSecond("F:\\temp.txt", "test2");
	}

	public void addContentFirst(String filePath, String newContent) {
		try {
			RandomAccessFile randomAccessFile=new RandomAccessFile(filePath, "rw");
			long fileLength=randomAccessFile.length();
			randomAccessFile.seek(fileLength);
			randomAccessFile.write(newContent.getBytes("UTF-8"));
			randomAccessFile.close();
		} catch (Exception e) {
		}
	}

	public void addContentSecond(String filePath, String newContent) {
        try {
			FileWriter fileWriter=new FileWriter(filePath, true);
			fileWriter.write(newContent);
			fileWriter.close();
		} catch (Exception e) {
		}
	}
