how to receive user input in java code example

Example 1: 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 2: 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 char

Example 3: user 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
  }
}
