| The input function displays its argument as a prompt and waits for input. When the user presses the Enter or Return key, the function returns a string representing the input text. The programmer then either leaves the string alone or converts it to the type of data that it represents (such as an integer).
Input a line of text as a string: name = input(“Enter your name: “) Input an integer: age = int(input(“Enter your age: “)) |
The Scanner class is used for the input of text and numeric data from the keyboard. The programmer instantiates a Scanner and uses the appropriate methods for each type of data being input.
Create a Scanner object attached to the keyboard: Scanner keyboard = new Scanner(System.in); Input a line of text as a string: String s = keyboard.nextLine(“Enter your name: “); Input an integer: int i = keyboard.nextInt(“Enter your age: “); Input a double: double d = keyboard.nextDouble(“Enter your wage: “); Caution: using the same scanner to input strings after numbers can result in logic errors. Thus, it is best to use separate scanner objects for numbers and text. |
