They still expect us to produce a report with totals (sums of their 2 or 3 integers)

PLEASE USE PYTHON PROGRAMMING LANGUAGE(OOP) Implement a class ComboLock that works like the combination lock in a gym locker. The lock is constructed with a combination—three numbers between 0 and 39. The reset method resets the dial so that it points to 0. The turnLeft and turnRight methods turn the dial by a given number of ticks to the left or right. The open method attempts to open the lock. The lock opens if the user first turned it right to the first number in the combination, then left to the second, and then right to the third. class ComboLock : def ComboLock(self, secret1, secret2, secret3) : def reset(self) : . . . def turnLeft(self, ticks) : . . . def turnRight(self, ticks) : . . . def open(self) :
Java - How do I output this statement as a horizontal statement with a newline? Everytime I use System.out.println, it makes the entire output vertical instead of horizontal. Program below. import java.util.Scanner; public class LabProgram { public static void main(String[] args) { int x; int y; Scanner scan = new Scanner(System.in); x = scan.nextInt(); y = scan.nextInt(); if(y >= x){ for(int i=x; i<=y; i = i + 5) { System.out.print(i+ " "); (The problem line) } } else{ System.out.print("Second integer can't be less than the first."); } }}
JAVA - Please produce both a product.java file and a productprinter.java file (tester) Implement a class Product. A product has a name and a price, for example new Product("Toaster", 29.95). Supply methods getName, getPrice, and reducePrice. Supply a program ProductPrinter that makes two products, prints each name and price, reduces their prices by $5.00, and then prints the prices again.
Java - How can I output the following statement as a single line with a newline? Program below. import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int n = sc.nextInt(); if(n>=11 && n<=100) { while(n>=11 && n<=100) { System.out.print(n+ " "); (the problem line. When I use System.out.println, it makes the line vertical when I want it horizontal.) if(n ==11||n==22||n==33||n==44||n==55||n==66||n==77||n==88||n==99) break; n--; } } else System.out.println("Input must be 11-100"); }}
Define the method inspectVals() with a Scanner parameter that reads integers from input until 0 is read. The method returns true if none of the integers read before 0 are 1000. Otherwise, the method returns false. Ex: If the input is 1005 1001 997 0, then the output is: 1000 not present import java.util.Scanner; public class ValueInspector { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); boolean valueNotPresent; valueNotPresent = inspectVals(scnr); if (valueNotPresent) { System.out.println("1000 not present"); } else { System.out.println("Found one or more 1000s"); } }}
. import java.util.Scanner;public class Main{public static void main (String args[]){ Scanner scan=new Scanner(System.in); System.out.print("Enter first number\n");int num1=scan.nextInt(); System.out.print("Enter second number\n"); int num2=scan.nextInt(); System.out.print("Enter Third number\n"); int num3=scan.nextInt(); findLargest(num1,num2,num3); }static void findLargest(int num1,int num2, int num3){ if(num1>=num2 && num1>=num3){ System.out.println(num1+" is the greatest number"); } else if(num2>=num1 && num2>=num3){ System.out.println(num2+" is the greatest number"); } else{ System.out.println(num3+" is the greatest number"); } 1.

Besides main() this program has one method that computes the amount of raise and the new salary for an employee. The current salary and a performance rating (a String: "Excellent", "Good" or "Poor") are input. import java.util.Scanner; public class Salary { public static void main (String[] args) { Declare variables Prompt for and read current salary and rating For an excellent rating compute raise as 0.06 of current salary For a good rating compute raise as 0.04 of current salary For a poor rating compute raise as 0.015 of current salary You can use abc.equals(“xyz”) to verify the rating read For an invalid rating display an appropriate message and display the salary without change; otherwise, compute and print new salary and raise amount main() must display the message } } Note:- Please type and execute this java program and also need an output for this java program as soon as possible.
