java - 如何在读取文件时删除空行

Question

我想知道如何在读取/写入文件时删除空行？

for(int i=1;i<=count;i++) {
    FileInputStream fistream1;
    try {
        name1="file1"+Integer.toString(i)+".txt";
        fistream1 = new FileInputStream(name1); // first source file
        fistream2 = new FileInputStream("Result.txt");  //second source file
        sistream = new SequenceInputStream(fistream2, fistream1);  
        fostream= new PrintWriter(new BufferedWriter(new FileWriter( result+".txt", true)));

        while( ( temp = sistream.read() ) != -1) {
            fostream.write(temp);   // to write to file
        }

        fostream.println("");
        fostream.close();
        sistream.close();
        fistream1.close();
        fistream2.close();
}

我找到了this code但由于以下行我无法实现它:

String line;
while((line = br.readLine())!= null) { ... }

他们使用 line 作为 String，但在我的例子中，我将 temp 作为 int:

int temp;
while((temp = sistream.read())!=-1) { ... }

有办法解决这个问题吗？

你可以尝试这样的事情:

while( ( temp = sistream.read() ) != -1) {
  if (!temp.trim().equals(""))
  {
    fostream.write(temp); // to write to file
  }
...
