Java Program - 01  

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.

Sample Output

Hello, World.
Hello, Java.

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.");

}
}

output:

Hello, World.
Hello, Java.

JAVA Program - 05 "JAVA Loops I"

Java Stdin and Stdout I   Program - 05 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 the characters. The second column contains the  integer , expressed in exact digits; if the original input has less than three digits, you must pad your output's leading digits with zeroes. Sample Input java 100...
