原来txt内容:
"我要添加内容"
import java.io.*; class Test {
public static void main(String[] args) {
FileWriter fw = null;
BufferedWriter bw = null;
String con = "tinyphp";
try {
fw = new FileWriter("e://d/add.txt", true); //加true
bw = new BufferedWriter(fw);
bw.write(con);
} catch (Exception e) {
System.out.println(e);
} finally {
try {
bw.close();
fw.close();
} catch (Exception e) {
System.out.println(e);
}
}
}
}
运行后:文本为
"我要添加内容tinyphp"
