analyze the following code //enter an integer scanner input = newScanner(System.in); int number = input.nextInt(); if (number <= 0) Syste.out.println(number);
To analyze this code properly lets give each line a number
Scanner input = new Scanner(System.in);
int number = input.nextInt();
if (number <= 0)
System.out.println(number);
Explanation:
In line one, an object of the Scanner class is created with an instance variable called input. The Scanner allows for the receiving of user input from the keyboard
In line two, an int variable number is created and assigned to the next integer received from the keyboard using the nextInt() method of class Scanner.
In line three is an if statement to check if the number entered at the keyboard is less or equal to zero
Line 4 outputs the number if the condition in line 3 is true.
