Java文件 - 打开文件并写入它 [英] Java File - Open A File And Write To It

问题描述

我知道我们应该在我们的问题中添加一段代码，但我非常傻眼，无法包裹我的头脑或找到任何可以遵循的例子。

I know we are supposed to add a snipit of code to our questions, but I am seriously dumbfounded and can't wrap my head or find any examples to follow from.

基本上我想打开已经包含内容的 C：\A.txt 文件，并在最后写一个字符串。基本上就是这样。

Basically I want to open file C:\A.txt , which already has contents in it, and write a string at the end. Basically like this.

文件A.txt包含：

John
Bob
Larry

我想打开它并在结尾写Sue所以现在文件包含：

I want to open it and write Sue at the end so the file now contains:

John
Bob
Larry
Sue

很抱歉没有代码示例，今天早上我的大脑已经死了....

Sorry for no code example, my brain is dead this morning....

BufferedWriter out = null;

try {
    FileWriter fstream = new FileWriter("out.txt", true); //true tells to append data.
    out = new BufferedWriter(fstream);
    out.write("\nsue");
}

catch (IOException e) {
    System.err.println("Error: " + e.getMessage());
}

finally {

        out.close();
    }
