java Use a loop to track the growth of the Utopian Tree. The tree grows exactly 1 cm for the first three years, and then afterwards it grows by 2 cm every year. Show the growth of the tree each year up to year 10. See the example flow below. Use the format: year x - growth x cm tree size: x cm where the 'x' values are different values of year, the growth amount, and the total tree size up to that year
Write a java program that simulates rolling a pair of dice 10,000 times and counts the number of times doubles (two of the same number) are rolled for each different pair of doubles. Use a loop, if-else statements and a random number generator. After the 10,000 iterations, print out the following results: Value of the first die Value of the second die Total number of dice rolls Number of snake eyes rolls (ones) Number of double two rolls Number of double three rolls Number of double four rolls Number of double five rolls Number of double six rolls
Write a program in OddIntegers.java that displays the first n positive odd integers and computes and displays their sum. For example, in n is 4, you should print the following to the screen:1 + 3 + 5 + 7 = 16
in java Integer numInts is read from input representing the number of integers to be read next. Use a loop to read the remaining integers from input into variable value. For each integer from 0 to numInts minus 1, inclusive, output the integer followed by " grapes". End each output with a newline. Click here for exampleEx: If the input is: 2 14 12 then the output is: 14 grapes 12 grapes 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 import java.util.Scanner; public class NumberOfGrapes { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumInts; intvalue; inti; numInts=scnr.nextInt(); /* Your code goes here */ } }
Write code which prints every number from 10 to 1 a number of times equal to the number itself (e.g. ten 10’s, nine 9's...). Every individual number printed should be separated by a space, and there should be a new line each time the number changes. You should use nested loops to produce your output (it will result in far less code). in JAVA Partial sample run: 10 10 10 10 10 10 10 10 10 10 9 9 9 9 9 9 9 9 9 8 8 8 8 8 8 8 8 ........
Write a java program that reads in three strings and sorts them alphabetically. You can ask to enter 3 strings in three separate lines. It doesn't have to be one line. (USE IF STATMENTS OR SWITCH STATMENTS, NO LOOPS OR ARRAYS) Ex: Enter three strings: Charlie Able BakerStrings in order: Able Baker Charlie
Using Java and using only the scanner class: Part B: For Loop Program Write a program to compute the sum of the first N Fibonacci numbers, where N is an integer that is input by the user. Once it computes the sum, the program will prompt the user for a new value of N. The program will exit if the user enters a non-integer number or string (such as “quit”) instead of an integer. Additionally: For both the above problems, the first four numbers of the Fibonacci sequence are: 0, 1, 1, and 2. Part A must use While loops only. Part B must use at least one For loop, but may also use while loops. Sample output and a suggested flowchart is provided for Part A, but not part B.
Write a program in Java to make such a pattern like right angle triangle with number increased by 1. The size of the triangle is measured by the number of rows that will be decided by the user. For example, if the user decides to print out a 3-row right triangle, your program should print out 1 2 3 4 5 6 If the user decides to print out a 4-row right triangle, your program should print out 1 2 3 4 5 6 7 8 9 10
Using .java Eclipse, Write a program that prompts the user for a U.S. dollar amount and then converts it to Japanese Yen, British Pound, and New Zealand currency. Once you calculate the conversion, print a single line with each converted currency only showing two decimal places, and its respective code (as shown in the example below): 10 U.S. Dollars in Egyptian Pound (exchange rate = 15.9976) would print as follows after conversion: 10.00 USD in Egyptian Pound is 159.98 EGP
JAVA: Write a program that reads an integer and prints how many digits the number has, by checking whether the number is ≥ 10, ≥ 100, and so on. (Assume that all integers are less than ten billion.) If the number is negative, first multiply it with –1.
WRITE IN JAVA USING JOptionPane.showInputDialog Write a program that reads a sentence as input and converts each word to “Pig Latin”. In one version of Pig Latin, you convert a word by removing the first letter, placing that letter at the end of the word, and then appending “ay” to the word. Here is an Example: English: I SLEPT MOST OF THE NIGHT Pig Latin: IAY LEPTSAY OSTMAY FOAY HETAY IGHTNAY EXAMPLE:
Write a Java program, GradeApp that reads a series of exam scores given as integers in the range 0 to 100. Display the total number of grades and the number of grades in each letter-grade category, followed class average (as a percentage with 2 decimal place): Use the value -1 as a sentinel value to indicate the end of the input. (The -1 value is used only to end the loop. Please do not use it in the calculations.)
