how to take input in java
import java.util.Scanner; // Import the Scanner class
class MyClass {
public static void main(String[] args) {
Scanner myObj = new Scanner(System.in); // Create a Scanner object
System.out.println("Enter username");
String userName = myObj.nextLine(); // Read user input
System.out.println("Username is: " + userName); // Output user input
}
}
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
Scanner in = new Scanner(System.in);
System.out.print("Please enter hour 1: ");
int hour1 = in.nextInt();
System.out.print("Please enter hour 2: ");
int hour2 = in.nextInt();
System.out.print("Please enter minute 1: ");
int min1 = in.nextInt();
System.out.print("Please enter minute 2: ");
int min2 = in.nextInt();
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 char
