in my c++ code n and m are two integer variables. But in your java code that variables are doesn't used. – Sumudu De Zoysa Sep 10 '15 at 06:17

try

  Scanner scanner=new Scanner(System.in);
    int m,n;
    while( (m =scanner.nextInt()) != -1 && (n=scanner.nextInt()) != -1) {
         //some logic
        System.out.println(m +"\t"+n);
    }

This is wrong. `nextInt` returns the scanned int, but `scanf` returns "the number of items of the argument list successfully filled" or EOF. – Emil Laine Sep 10 '15 at 07:20
