[java] How to read until end of file (EOF) using BufferedReader in Java?

I have problem with reading the input until EOF in Java. In here, there are single input and the output consider the input each line.

Example:

input:

1
2
3
4
5

output:

0 
1
0
1
0

But, I have coded using Java, the single output will printed when I was entering two numbers. I want single input and print single output each line (terminate EOF) using BufferedReader in Java.

This is my code:

BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
StringBuffer pr = new StringBuffer("");

String str = "";
while((str=input.readLine())!=null && str.length()!=0) {
    BigInteger n = new BigInteger(input.readLine());
}

With text files, maybe the EOF is -1 when using BufferReader.read(), char by char. I made a test with BufferReader.readLine()!=null and it worked properly.
