Java Scanner comparision.

“Scanner can not be compared to int.” I have searched this question up and have found the .equals() function. Is there a greater than or less than function? Thanks.

Code214 Yes because a is a object of scanner class and you can't compare with integer. To compare get integer value from scanner object like Scanner sc = new Scanner ( System.in); int a = sc.nextInt(); if (a > 2) { }

equals method use to compare String. To check greater than or less than use > or < like a > b or a < b

You forgot the reading-step, this code ignores any input... Hint: scanner.next*
