scanner in java
import java.util.Scanner; //Import Scanner in java
class classname{
public void methodname(){
Scanner s_name = new Scanner(System.in); //Scanner declaration
//Use Scanner object to take input
int val1 = s_name.nextInt(); //int
float val2 = s_name.nextFloat(); //float
double val3 = s_name.nextDouble(); //double
string name = s_name.nextLine(); //string
char ch = s_name.nextLine().charAt(0); //character
}}how to use scanners in java
import java.util.Scanner;
Public class Scanner {
Public static void main(String[] args) {
// Scanner *scanner name here* = new Scanner(System.in);
Scanner scan = new Scanner(System.in);
System.out.println("Type anything and the scanner will take that input and print it");
String next = scan.next();
System.out.println(next);
}
}Java scanner example
import java.util.Scanner;
public class AddTwoNumbers2 {
public static void main(String[] args) {
int num1, num2, sum;
Scanner sc = new Scanner(System.in);
System.out.println("Enter First Number: ");
num1 = sc.nextInt();
System.out.println("Enter Second Number: ");
num2 = sc.nextInt();
sc.close();
sum = num1 + num2;
System.out.println("Sum of these numbers: "+sum);
}
}
Output:java scanner functions
import java.util.Scanner;
public class scanners{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
// Reading int
