program to get User Input in java


import java.util.Scanner;
public class UserInput
{
public static void main(String args[])
{
Scanner obj=new Scanner(System.in);
int number;
String str;
float f;
System.out.println("Enter the String? :");
str=obj.nextLine();
System.out.println("You have entered the string:"+str);
System.out.println("Enter the number ?");
number=obj.nextInt();
System.out.println("You have entered the number:"+number);
System.out.println("ENter the float number");
f=obj.nextFloat();
System.out.println("YOu have entered the float value:"+f);
}
}

java.util has a class named “scanner” which is used to read different types of values from users.


Scanner obj=new Scanner(System.in);

In this statement Scanner is the class name,obj is the Object of the Scanner class and System.in is the input stream.

str=obj.nextLine();

nextLine() is used to get a line from the user,similarly nextInt() and nextFloar are used to get Integers and float from the users
