System.in.read() method

Question

Following is the code, I have written to get two inputs from user. But when I run the program, It takes only one input and generate other by itself and calculate the wrong v

Answer 1

System.in is an InputStream - read() reads exactly one byte. Your direct input is more than one byte and so both values are directly read within the first input.

Use a Scanner instead (with System.in as Input):

 Scanner sc = new Scanner(System.in);
 int i = sc.nextInt();
