如何在属性文件中写入？

-3

我有一个属性文件“jpg2dcm.cfg”，女巫的属性是默认设置的。所以，我不得不添加属性值。如何修改文件以使用java设置属性值？如何在属性文件中写入？

jpg2dcm.cfg：

“巫婆”你说？！无论如何......如果它只是一个文本文件，为什么不打开它来写作，进行更改并保存呢？ – durbnpoisn

而你并没有追随已经出现过的无数指南之一，因为.....？ – redFIVE

这是一个太宽泛的问题。你不知道该怎么做？将文件读入一个属性对象，操作它还是把它写回来？ – Sid

阅读使用的FileReader像这样的文件：

FileReader fileReader = new FileReader(filename); 
BufferedReader br = new BufferedReader(fileReader); 
String line; 
while((line= br.readLine()) != null) { 
System.out.println(line); 
//Do what you need after reading the file. 
} 
fileReader.close();

修改你需要修改或你需要用它工作的字符串后，只写了新文件在同一位置上的同名像这样：

FileWriter writer = new FileWriter(filename); 
writer.write(newStringToWriteInFile); 
writer.close();
