5. INPUT

Hi friends what's up.I hope you are well.In last tutorial we are learning about if-else statement.Today we will learning how to take input from keyboard.

First we see a code which can take input..........
take a class named inputt.


import java.util.Scanner;
public class inputt {
      public static void main(String args[]){
     Scanner pavel = new Scanner(System.in);
     
     String Mostafij = pavel.nextLine();
     System.out.println(Mostafij);
      }
}


output

Hi I love you                                    (that's i input from keyboard)

Hi I love you

Here we make a class named inputt. At the top we import  java.util.Scanner.It is very important.
then we take a Scanner variable pavel and initialized as new Scanner input. Then we take a String variable Mostafij & initialized in by what we input from keyboard.For taking String we have to wright Scanner_variable.nextLine().


for int variable



import java.util.Scanner;
public class inputt {
      public static void main(String args[]){
       Scanner pavel = new Scanner(System.in);
       
       int Mostafij = pavel.nextInt();
       System.out.println(Mostafij);
      }
}

For taking integer we have to wright Scanner_variable.nextInt().

for float variable

import java.util.Scanner;

public class inputt {

      public static void main(String args[]){

       Scanner pavel = new Scanner(System.in);

       

       float Mostafij = pavel.nextFloat();

       System.out.println(Mostafij);

      }

}

For taking float we have to wright Scanner_variable.nextFloat().

for double variable

import java.util.Scanner;
public class inputt {
      public static void main(String args[]){
       Scanner pavel = new Scanner(System.in);
       
       float Mostafij = pavel.nextFloat();
       System.out.println(Mostafij);
      }
}
For taking idouble we have to wright Scanner_variable.nextDouble().

Here it is........end.See you in next tutorial.Till then be safe.
