Practical live demo on the program for taking input using scanner class in java.
What are the methods for taking input in java?
There are two methods for taking input in java:-
Command Line Argument : In this method we give input from command line, when we are going to execute the program at DOS command prompt. In this method we need to type cast the string argument in different data types. Because command line arguments are received in String and we can not use String in arithmetical operation. So we need to translate String in to corresponding data type.
Scanner Class : It is a class of java.util package. It provides methods for different data type. For using Scanner Class, we need to import java.util.* package then create an object of scanner class. Then we call the required method of scanner class using their object.
How to take input using Scanner class?
import java.util.*;
class ScannerDemo
{
public static void main(String st[])
{
Scanner input=new Scanner(System.in);
System.out.println("Enter two nos :");
int a=input.nextInt();
int b=input.nextInt();
int c=a+b;
System.out.println("Result = "+c);
}
}
What are different function in Scanner class?

next(); For String data type
nextLine(); For String data type
nextBoolean(); For boolean data type
nextByte(); For byte data type
nextShort(); For short data type
nextInt(); For int data type
nextLong(); For long data type
nextFloat(); For float data type
nextDouble(); For double data type
