What would the following statement, when used in a Java program,
display on the screen?
System.out.println("Java is great!");
Step by step
Solved in 2 steps
- First code is top, second code is on bottom. This is for Java. What makes these two codes different? (a) If x = 3, what will the first (code) print out? (b) If x = 3, what will the second (code) print out? (c)If x = 1, what will the first (code) print out? (d) If x = 1, what will the second (code) print out?14. How can you check whether two numbers x and y are equal or not without using the == operator in JAVA.T/F 3. The symbols "=" and "==" are used interchangeably in Java.
- Java programming If you wanted to know the position of the letter v (i.e. return 2) in the String str containing the word "Java", which of the following code should you use? * mid (2,str); str.indexOf('v'); str.charAt(2); str.position('v'); indexOf(str,'v');IN JAVA CODE: Please make a Huffman program code that will allow the user to do the following: Input a series of characters (sentence, phrase, paragraph, etc.) as basis for the creation of the Huffman code. Input a text that will be converted to Huffman code. Input a Huffman code that will be converted to its text equivalent.java a. You want to create a Java main class. You create the source code file, declare the package, and write the class header. Now you must create the main method that starts the program. Write the entire method header, including the opening brace for the method. b. Assume that price is an integer variable whose value is the price (in US currency) in cents of an item. Write a statement that calculates the whole dollars in the amount and saves it in a new integer variable named dollars. Note: The Java style guide states that one space is used on either side of binary operators.
- Given the following Java code: String str1 = “Java is useful!”; String str2= “Java is cool”; write the result of to each of the following questions: str1.charAt(15) str1.substring(2, 9)Java Programming: The program will figure out a number chosen by a user. Ask user to think of a number from 1 to 100. The program will make guesses and the user will tell the program to guess higher (h) or lower (l). Sample run of the program might look like below : Guess a number from 1 to 100. (here, the user is thinking of 81) Is it 50? (h/l/c): h Is it 75? (h/l/c): h Is it 88? (h/l/c): l Is it 81? (h/l/c): c Great! Do you want to play again? (y/n): y Guess a number from 1 to 100. (here the user is thinking 37) Is it 50? (h/l/c): l Is it 25? (h/l/c): h Is it 37? (h/l/c): c Great! Do you want to play again? (y/n): n our program should implement the binary search algorithm. Every time the program makes a guess it should guess the midpoint of the remaining possible values. Consider the first example above, in which the user has chosen the number 81: On the first guess, the possible values are 1 to 100. The midpoint is 50. The user responds by saying “higher” On the second…LANGUAGE: JAVA Equal numbers: Given three integers, determine how many of them are equal to each other. Theprogram must print one of these numbers: 3 (if all are the same), 2 (if two of them are equal toeach other and the third is different) or 0 (if all numbers are different).
- In JAVA ASSIGNMENT DESCRIPTION: A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("After 6 hours: %.2f mg\n", yourValue); Ex: If the input is: 100 the output is: After 6 hours: 50.00 mg After 12 hours: 25.00 mg After 24 hours: 6.25 mg Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg. THE CODE I HAVE SO FAR: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); double caffeineMg; // "double" supports floating-point like 75.5, versus int for integers like 75. caffeineMg = scnr.nextDouble(); System.out.printf("After…Correct the following wrong statements. In Java, once a variable is declared in a method as local variable, it will be visible and could be used in any other method in the program.Java - How do I output the statement exactly as it shows? How can I get rid of the commas at the end? Don't get rid of each comma, just the ones at the end of the output.
