Let’s understand a scanner class using one java scanner program. Java import java.util.Scanner; class PrepBytes { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.print("Enter the number: "); int number= sc.nextInt(); System.out.println("...
import java.util.Scanner; public class DiamondPatterForLoop { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("Enter Pattern Size : "); int size = sc.nextInt(); System.out.print("Enter Symbol : "); char symbol = sc.next().charAt(...
In this article, we are going to read string with two different methods StringReader and Scanner class with example, output and explanation. Submitted by IncludeHelp, on November 24, 2017 This an example of Java string programs, In this java program, we have to read strings using '...
In the above program, we imported the "java.util.*" package to use the Scanner class. Here, we created a public class Main that contains a main() method.The main() method is the entry point for the program. And, created a variable num of integer type and then we used Math.multiply...
import java.util.Scanner; class laptop{ private String modelNumber; private boolean hasFan; private float ramSpeed; protected int numCores; //private String input; [code]... Without the setInfo() in the laptop class the program functions as desired but i intend to ask the user if he wants...
Peek():The time complexity of peek is also O(1) as we are just getting the last element from the array/list. The auxiliary space is also O(1) as we are not using any extra space. So, we have seen how to create our own stack class in Java. However, every time we need a stack...
import java.util.Scanner; /**This program keeps track of user's active time in minutes for a month**/ public class ActiveMinutesDay { public static void main(String[] args) { //Get user input using scanner Scanner in=new Scanner(System.in);...
import java.util.Scanner; class MyClass { public static void main(String[ ] args) { String str; Scanner myVar = new Scanner(System.in); str=myVar.nextLine(); if(str=="yes") { System.out.println("yes"); } else{ System.out.println("No"); } } } so i created String and get th...
import java.util.Scanner; public class HelloWorld { public static void main(String[] args) { // Creates a reader instance which takes // input from standard input - keyboard Scanner reader = new Scanner(System.in); System.out.print("Enter a number: "); // nextInt() reads the next in...
In a menu-driven program or a game, we require an option to restart or reset our program. We can restart a program in Java by recursively calling a function or using conditional loop statements. Use ado-whileConditional Statement importjava.util.*;importjava.util.Scanner;classMain{publicstatic...
