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 ... inputhow 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);//outputhow 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");

}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:static scanner java
import java.util.Scanner;
class ComputerScienceHomework16 {
// making it static in other functions
static Scanner scanner = new Scanner(System.in);
public static void test(){
System.out.print("type a number: ");
int num = scanner.nextInt();
System.out.println("you typed the number " + num);
}
