我有两个文件说
abc 光盘 sfh t fgh
和另一个文件
啊啊 o k io abc 光盘
我想比较这两个文件并获取输出文件
abc 光盘 sfh t fgh 啊啊 o k io
这是我的代码
public static void MergeFiles(final File priviousModifiedFilesList, final File currentModifiedFilesList,
final File ModifiedFilesList) {
FileWriter fstream = null;
out = null;
try {
fstream = new FileWriter(ModifiedFilesList, true);
out = new BufferedWriter(fstream);
}
catch (IOException e1) {
e1.printStackTrace();
}
System.out.println("merging: " + priviousModifiedFilesList + "\n");
System.out.println("merging: " + currentModifiedFilesList);
FileInputStream fis1;
FileInputStream fis2;
try {
fis1 = new FileInputStream(priviousModifiedFilesList);
BufferedReader bufferedReader1 = new BufferedReader(new InputStreamReader(fis1));
fis2 = new FileInputStream(currentModifiedFilesList);
BufferedReader bufferedReader2 = new BufferedReader(new InputStreamReader(fis2));
String Line1;
String Line2;
while (((Line1 = bufferedReader1.readLine()) != null)) {
while ((Line2 = bufferedReader2.readLine()) != null) {
if (Line1.equals(Line2)) {
out.write(Line1);
}
out.write(Line2);
out.newLine();
}
out.write(Line1);
}
bufferedReader1.close();
bufferedReader2.close();
}
catch (IOException e) {
e.printStackTrace();
}
out.close();
}
它写入第一个文件中的所有行，并且当这些行匹配时停止。
