How do you use the Scanner class to store two words or more in a String variable then the next input in another String variable in java?
Scanner scan = new Scanner("[input method]"); // input method could they key board //(System.in) or a String String one = scan.next() + scan.next(); // get the first 2 words and concatenate String two = scan.next(); // the remaining word
How do you accept an integer or a float or double value as a console input from user in java also you do not want to use command line arguments?
Scanner scan = new Scanner(System.in); // A scanner object that reads from the // keyboard( System.in), must import //Scanner class to use this System.out.print("Input Integer: "); int first = scan.nextInt(); //Reads the next int after the printed stuff that the user //inputs System.out.print("Input Double: "); double first = scan.nextDouble(); //Reads the next double after the printed stuff that //the user inputs
How you can restrict the user to input only digits or integers?
import java.util.*;public class tryint{public static void main(String[] args){Scanner s=new Scanner(System.in);int w;try{System.out.print("Input number:");w=s.nextInt();System.out.print("Input number is "+w);}catch(Exception wi){System.out.println("not an integer");}}}
Java program to give input of a string and display it?
import java.util.*; public class Example { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.println("Please enter a string:"); String input = in.next(); System.out.println("The String you entered is: " + input); } }

How would i write a program that takes an integer as an input and reverses its digits as an output?
In java you can do it like this: import java.util.Scanner; public class Sample { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Input an integer: "); int i = input.nextInt(); System.out.print("reverse:"); while(i != 0) { System.out.print(i % 10); i = i / 10; } } }

Why does Java accept any input as string by default?
Java doesn't always accept any input as a string it only do that when the input is entered from the " JOptionPane.InputDialog" but it can accept any other data type like integer or short from the console though Scanner class .

How would you write java script code that will prompt a user to enter a number between 1 and 10 and give an error message if its not and continue to prompt them until the proper value is received?
For this, I'll just go ahead and write a sample program: (assume all necessary imports are present) public class prompter{ public static void main(String[] args){ Scanner kb = new Scanner (System.in); int inputValue = 0; System.out.println("Enter a value between 1 and 10:"); String input = kb.nextLine(); try{ inputValue = Integer.parseInt(input); } catch( Exception e) {} while( inputValue < 1 inputValue > 10 ){ System.out.println("Invalid value.\nPlease enter a value between 1 and 10:"); input = kb.nextLine(); inputValue = Integer.parseInt(input); } /* enter whatever code you want here - inputValue will contain an inputted integer between 1 and 10*/ } } This sample program uses Scanner objects to detect user input, and uses the Integer class's parseInt() method to interpret that input, using a try/catch statement to first make sure that the input is in fact an integer.
