Java regex not working for the input string in the second line

I have the below code which works perfectly when I pass these parameters from the console.

Test-case

{"012.99 008.73","099.99 050.00","123.45 101.07"}

Source code

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Pass the parameters");
String line=br.readLine();
String str=line.replaceAll("[^0-9 A-Z a-z /, .]","");
String[] nos=str.split(",");

for(String s:nos){
    System.out.print(s+"\t");
}

But the above code does not work when i pass the below parameters from the console. 

{"612.72 941.34","576.46 182.66","787.41 524.70","637.96 333.23","345.01 219.69",
 "567.22 104.77","673.02 885.77"}

The String array nos is missing out the strings "567.22 104.77","673.02 885.77" in the second line.

Please help me on this.

It is not working because you are reading only first line.

Here, You need to read all line in a string. Then use regex on it.

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Pass the parameters");
String line;

StringBuffer sb = new StringBuffer("");
while ((line = br.readLine()) != null) {
    sb.append(line);
}
line = sb.toString();

String str=line.replaceAll("[^0-9 A-Z a-z /, .]","");
String[] nos=str.split(",");

for(String s:nos){
    System.out.print(s+"\t");
}
