Answer 1

Use the Scanner class as shown in this article.

Answer 2

import java.util.*;

class Array

{

public static void main(String args[]){

    Scanner sc=new Scanner(System.in);

      int n =sc.nextInt();

     System.out.println(n);

}

}

Answer 3

we use Scanner class to take user input in java as shown below example

incase text files we use BufferReader class  to take input from user

import java.util.*;

class InputByUser {

    public static void main(String[] args) {

        Scanner sc =new Scanner(System.in);

        int a=sc.nextInt();//for integer

        double b=sc.nextDouble();//for floating values

      System.out.println(a);
    }

}

Answer 4

//For take input from user

import.java.util.Scanner;

class Input

{

     public static void main(String args[])

        {

             Scanner obj = new Scanner(System.in)

                 int n;

                 n=obj.nextInt();

                  System.out.println("User Inputting Number is "+n);

       }

}

Answer 5

Scanner sc=new Scanner (System.in);

int a=sc.next Int();

Answer 6

import java.util.*;
class Main
{
public static void main(String[] args)
{
Scanner sc= new Scanner(System.in);
System.out.print("Enter first number- ");
int a= sc.nextInt();
}
}

Answer 7

import java.util.*;//use to take input

public class Main{

public static void main(String[] args){

Scanner sc = new Scanner(System.in);

int a = sc.nextInt();//for integer value

Double b = sc.nextDouble();//for decimal value

Boolean c = sc.nextBoolean(); // for true false

char d = sc.nextChar(); // for character

String s = sc.nextString(); // for string

System.out.println( b);

System.out.println( a);

System.out.println( c);

System.out.println( d);

System.out.println( s);

}

}

Answer 8

Let's understand it with the help of a simple code example

import java.util.Scanner;

public class UserInputExample {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.print("Enter a number: ");
        int number = scanner.nextInt();

        System.out.println("You entered: " + number);

        scanner.close();
    }
}

Well, in the above code example, it takes a number as input from the user and will display that number as output.

Thanks

The Scanner class is used to get user input, and it is found in the java.util package.

Answer 10
