Can any one explain getting user input program in simple practical way

Answer 1

Getting a user input is little long process in java compare to then language like python or C++.
1. First you need to import Scanner package. On the top of program:-
import java.util.Scanner;

2. Create an object of the Scanner class so the Scanner methods can be called using the Scanner object.
Scanner s = new Scanner (System.in);
3. Then you use the different scanner methods to input different data types from user. Example:-
int a = s.nextInt();
This will put the user input integer value to variable "a".
float b = s.nextFloat();
String c = s.nextLine();
And so on... Make sure to use the specific methods for specific datatyped like nextInt() method only for integer values.

Answer 6

import java .io.*;
Class simple
{
Scanner in=new Scanner(System.in);
int i=Scanner.nextInt();
}
Here Scanner an inbuilt class is used to get the input from the variable in ,new keyword is used to allocate memory for in and used for reference,System is another class to access in variable from the system.
Now int is a datatype,I is a variable and Scanner is again a class,and nextInt() method is used to convert input strings of digits to integer .

Answer 11

The difference betwixt alert, prompt, and confirm:
Alert tells the user what your code is about. You don't need a variable for this unless you want to have the alert apart of your code.
confirm lets the user pick between ok or cancel.You need to put a variable for it. If ok is chosen, the system returns as true. You can use this to your advantage if you start an if statement saying if the confirm is true what happens and if the confirm is false what happens.
prompt is input. You need to make a variable of the prompt. This tells the system that it will read whatever answer the user puts in. You can also use this in if statements to your advantage.
