Hacker Rank task

[Akilrames]

Welcome to Java! Welcome to the world of Java! In this challenge, we practice printing to stdout. The code stubs in your editor declare a Solution class and a main method. Complete the main method by copying the two lines of code below and pasting them inside the body of your main method. System.out.println("Hello, World."); System.out.println("Hello, Java."); Input Format There is no input for this challenge. Output Format You must print two lines of output:

1. Print Hello, World. on the first line.
2. Print Hello, Java. on the second line. */

public class Solution {

public static void main(String[] args) {
    /* Enter your code here. Print output to STDOUT. Your class should be named Solution. */
 System.out.println("Hello, World.");
    System.out.println("Hello, Java.");
}

}

Task In this challenge, you must read 3 integers from stdin and then print them to stdout. Each integer must be printed on a new line. To make the problem a little easier, a portion of the code is provided for you in the editor below. Input Format There are 3 lines of input, and each line contains a single integer. */

public class Solution {

public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);
    int a = scan.nextInt();
    // Complete this line
    // Complete this line
    int b = scan.nextInt();
    int c = scan.nextInt();
    scan.close();

    System.out.println(a);
    // Complete this line
    // Complete this line
    System.out.println(b);
    System.out.println(c);
}

}

Task Given an integer, , perform the following conditional actions: If is odd, print Weird If is even and in the inclusive range of to , print Not Weird If is even and in the inclusive range of to , print Weird If is even and greater than , print Not Weird Complete the stub code provided in your editor to print whether or not is weird. Input Format A single line containing a positive integer, . Constraints Output Format Print Weird if the number is weird; otherwise, print Not Weird. Sample Input 0 3 Sample Output 0 Weird Sample Input 1 24 Sample Output 1 Not Weird */

}

}

In this challenge, you must read an integer, a double, and a String from stdin, then print the values according to the instructions in the Output Format section below. To make the problem a little easier, a portion of the code is provided for you in the editor.

Note: We recommend completing Java Stdin and Stdout I before attempting this challenge.

Input Format

There are three lines of input:

The first line contains an integer. The second line contains a double. The third line contains a String. Output Format

There are three lines of output:

On the first line, print String: followed by the unaltered String read from stdin. On the second line, print Double: followed by the unaltered double read from stdin. On the third line, print Int: followed by the unaltered integer read from stdin. To make the problem easier, a portion of the code is already provided in the editor.

Note: If you use the nextLine() method immediately following the nextInt() method, recall that nextInt() reads integer tokens; because of this, the last newline character for that line of integer input is still queued in the input buffer and the next nextLine() will be reading the remainder of the integer line (which is empty).

Sample Input

42 3.1415 Welcome to HackerRank's Java tutorials! Sample Output

String: Welcome to HackerRank's Java tutorials! Double: 3.1415 Int: 42

import java.util.Scanner;

public class Solution {

public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);
    int i = scan.nextInt();
    double d = scan.nextDouble();
    scan.nextLine();
    String s = scan.nextLine();
    scan.close();
    // Write your code here.

    System.out.println("String: " + s);
    System.out.println("Double: " + d);
    System.out.println("Int: " + i);
}

}

Java's System.out.printf function can be used to print formatted output. The purpose of this exercise is to test your understanding of formatting output using printf.

To get you started, a portion of the solution is provided for you in the editor; you must format and print the input to complete the solution.

Input Format

Every line of input will contain a String followed by an integer. Each String will have a maximum of alphabetic characters, and each integer will be in the inclusive range from to .

Output Format

In each line of output there should be two columns: The first column contains the String and is left justified using exactly characters. The second column contains the integer, expressed in exactly digits; if the original input has less than three digits, you must pad your output's leading digits with zeroes.

Sample Input

java 100 cpp 65 python 50 Sample Output

================================ java 100 cpp 065 python 050

Explanation

Each String is left-justified with trailing whitespace through the first characters. The leading digit of the integer is the character, and each integer that was less than digits now has leading zeroes.

import java.util.Scanner;

public class Solution {

public static void main(String[] args) {
        Scanner sc=new Scanner(System.in);
        System.out.println("================================");
        system.out.println("                                

for(int i=0;i<3;i++)

        {
            String s1=sc.next();
            int x=sc.nextInt();
            System.out.printf("%-15s%03d%n",s1,x);
        }
        System.out.println("================================");

}
