Change " " to "\\\\s+" in split function.

public static void main(String args[]) throws IOException {
    root = new trienode();

    System.out.println("enter inputs");
    BufferedReader s = new BufferedReader (new InputStreamReader(System.in));
    String[] s1 = s.readLine().split("\\s+");
    int  n = Integer.parseInt(s1[0]);
    int  l = Integer.parseInt(s1[1]);

    for(int i=0;i<n;i++)
    {

        String[] s2 = s.readLine().split("\\s+");
        String key=s2[0];
        int w=Integer.parseInt(s2[1]);
        //Insert(key , w);
    }

    for(int j=0;j<l;j++)
    {
        String s3 = s.readLine();
        if(search(s3)!=-1)
        System.out.println(search(s3));
    }

}
