3. Streams
4. Scanner

Streams
1. Streams are objects representing source or destination of data
2. They are ordered sequence of bytes (length undefined)

Scanner
1. Breaks the input into tokens using a delimiter
2. Simple text scanner that can parse primitive types + Strings
3. Delimiter is whitespace by default
4. Possible to set delimiter using useDelimiter function

public String next() - Returns the next token
public String nextLine() - Returns the next line as a String
public byte nextByte() - Returns the next token as byte
public int nextInt() - Returns the next token as integer
public short nextShort() - Returns the next token as short

import java.util.*;
public class Pattern{
public static void main(String args[]){
Scanner sc=new Scanner(System.in);

System.out.println("Enter your age ");
int age=sc.nextInt();

System.out.println("Enter your name ");
String name=sc.nextLine();

System.out.println("Enter your income");
double income=sc.nextDouble();

System.out.println(age);
System.out.println(name);
System.out.println(income);
