Reading input in java code example

Example 1: java scanner

import java.util.Scanner;

// import scanner 

Scanner myScanner = new Scanner(System.in); // Make scanner obj

String inputString = myScanner.nextLine(); // Take whole line

boolean inputBoolean = myScanner.nextBoolean(); //Boolean input

long inputLong = myScanner.nextLong(); //Interger,long ... input

Example 2: how to take input in java

Scanner sc = new Scanner(System.in);  // Create a Scanner object
String userName = sc.nextLine();//read input string
int age = sc.nextInt(); //read input integer
long mobileNo = sc.nextLong(); //read input long
double cgpa = sc.nextDouble(); //read input double
System.out.println(userName);//output

Example 3: java taking console input

String str = System.console().readLine();

Example 4: how to read input in java

//For continues reading a line
import java.util.Scanner; 

Scanner in = new Scanner(System.in); 
while(in.hasNextLine()) {
   String line = in.nextLine();
   System.out.println("Next line is is: " + line); 
}

3 ways to read input from console in java
-----------------------------

1. Using BufferedReader Class
2. Using Scanner Class
3. Using Console Class 

//bufferedreader class

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
...
public static void main(String[] args) throws IOException
...
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String name = reader.readLine();

//Scanner class

import java.util.Scanner;
...

String name = new Scanner(System.in);

//Console class:

String name = Syste.console().readLine();
