in java Strings itemToFind and inputItem are read from input. Integer wordCount is initialized with 1. Write a while loop that iterates until inputItem is equal to "Done". In each iteration of the loop: Increment wordCount if inputItem is equal to itemToFind. Read string inputItem from input. Click here for example Note: Assume that input has at least two strings. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 import java.util.Scanner; public class SimpleWhileLoop { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); StringitemToFind; StringinputItem; intwordCount; itemToFind=scnr.next(); inputItem=scnr.next(); wordCount=1; /* Your code goes here */ System.out.println(itemToFind+" occurs "+wordCount+" time(s)."); } }
When the given integer variable numberOfTools is: less than 14, output "Small tool box". between 14 inclusive and 39 inclusive, output "Mid-sized tool box". greater than 39, output "Need wall storage". End with a newline. Ex: If the input is 13, then the output is: (in java) Given Code: import java.util.Scanner; public class ToolDetails {public static void main(String[] args) {Scanner scnr = new Scanner(System.in);int numberOfTools; numberOfTools = scnr.nextInt();
Complete the convert() method that casts the parameter from a double to an integer and returns the result.Note that the main() method prints out the returned value of the convert() method. Ex: If the double value is 19.9, then the output is: 19 Ex: If the double value is 3.1, then the output is: 3 code: public class LabProgram { public static int convert(double d){ /* Type your code here */ } public static void main(String[] args) { System.out.println(convert(19.9)); System.out.println(convert(3.1)); }}
Given an integer, return the sum of all the odd numbers starting from 1. Assume the input will always be greater than 2. Ex: If the input is: 20 the output is 1+3+5+7+9+11+13+15+17+19: 100 449182.3196742.qx3zqy7 LAB ACTIVITY 1 import java.util.Scanner; 3 public class LabProgram { 4 5 6 7 8 9 10 13.3.1: CodingBird (Loop): Sum Even public static void main(String[] args) { /* Type your code here. */ } LabProgram.java 0/10 Load default template...
Examine this code and determine what happens when it is run: 1 public class Test { int x; 2 3 public Test(String t){ System.out.println("Test"); } public static void main(String[] args) { Test test = new Test ("boo"); System.out.println(test.x); } 4 5 6 7 8 10 } The program has a compile error because Test does not have a default constructor. The program has a compile error because System.out.println method cannot be invoked from the constructor. ) The program runs successfully and prints out: Test O The program has a compile error because you cannot create an object from the class that defines the object.
Type two statements using nextInt() to print two random integers between (and including) 0 and 9. End with a newline. Ex: 7 Note: For this activity, using one statement may yield different output (due to the interpreter calling randGen.nextInt() in a different order). Use two statements for this activity. (Notes) 1 import java.util.Scanner; 2 import java.util.Random; 3 4 public class DiceRoll { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); = new Random(); 5 6. 7 Random randGen 8 int seedVal; 9. 10 seedVal = scnr.nextInt(); 11 randGen.setSeed(seedVal);
Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A, B, C, D, E" is correct. Each question has one correct answer. Thank you. Part 1 - Given the following code, the output is __. class Sample{ public static void main (String[] args){ try{ System.out.println(5/0);}catch(ArithmeticException e){ System.out.print("Divide by zero????");}finally{ System.out.println("5/0"); } }} A. Divide by zero????B. 5/0C. Divide by zero????5/0D. 5/0Divide by zero????E. "5/0" Part 2 - Given the following code, the output is __. try{ Integer number = new Integer("1"); System.out.println("An Integer instance.");}catch (Exception e){ System.out.println("An Exception.");} A. An Integer instance.B. An Exception.C. 1D. Error: ExceptionE. None of the options

In Java: Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.
