if(x>=Byte.MIN_VALUE && x<=Byte.MAX_VALUE) System.out.println("* byte"); if(x>=Short.MIN_VALUE && x<=Short.MAX_VALUE) System.out.println("* int"); if(x>=Integer.MIN_VALUE && x<=Integer.MAX_VALUE) System.out.println("* short"); if(x>=Long.MIN_VALUE && x<=Long.MAX_VALUE) System.out.println("* long"); }

                    In my code also the test case is not satisffying...........
