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);//outputjava read input from user
import java.util.Scanner; /* Required Import*/
public class reading{
public static void main(String[] args){
Scanner scan = new Scanner(System.in); // Create Reader
System.out.print("Enter Your Age"); // Ask the user for something
int age = scan.nextInt(); // Read value from user
System.out.print(age); // Output the value
}
}
/*
Java Reading Options:
1_ reading int => nextInt();
2_ reading char => next().charAt(0); Single Character
3_ reading string => next();
4_ reading double => nextDouble();
*/java get input
Scanner sc = new Scanner(System.in);
String s = sc.next();
int n = sc.nextInt();
double d = sc.nextDouble();
float f = sc.nextFloat();
// more fast way
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String s = br.readLine(); // read line
int c = br.read(); // read single charhow to get user input in java
