Can we choose input variable as double?

If they are the same, then the number can be treated as an integer, otherwise a double (assuming you don’t need to worry about large numbers like longs).

What is hasNext in Java?

The hasNext() method checks if the Scanner has another token in its input. A Scanner breaks its input into tokens using a delimiter pattern, which matches whitespace by default. That is, hasNext() checks the input and returns true if it has another non-whitespace character.

How to input multiple values from user in one line in Java?

How to input multiple values from user in one line in Java? To input multiple values from user in one line, the code is as follows − A class named Demo contains the main function, inside which a Scanner class object is created, and two values, one double and one integer values are parsed.

How to take multiple inputs from the same input line?

To take multiple inputs from the user from the same input line, you can ask the user to seperate the input with a comma or a white space. In case of a white space, Anderson Vieira’s answer gives the correct idea. You can use 2 successive nextInt () statements as in System.out.println (“Enter 2 nos.”); int a = sc.nextInt (); int b = sc.nextInt ();

How are the values taken from the input?

The values are taken from the standard input and then displayed on the console. The Scanner object parses the input directly, without splitting it into multiple strings. In addition to this, the user can input the data on a single line or on multiple lines.
