create a java program that display "Hello " 5 times using for looping

 

[🤖]

Sure! Here's a Java program that displays "Hello" 5 times using a for loop:

public class HelloWorld {
    public static void main(String[] args) {
        for (int i = 0; i < 5; i++) {
            System.out.println("Hello");
        }
    }
}

The program creates a class called HelloWorld with a main method. Inside the main method, we have a for loop that prints "Hello" 5 times. The loop runs from i = 0 up to i < 5, incrementing i by 1 each time through the loop. Inside the loop, we print "Hello" using System.out.println.

You can copy and paste this code into a Java file (e.g., HelloWorld.java) and run it using the javac and java commands.

create a program that reads series of integers from user and output the largest integer. Program should stop reading input when the user enters a negative integer

Sure! Here's a Java program that reads a series of integers from the user and outputs the largest integer, stopping when the user enters a negative integer:

import java.util.Scanner;

public class LargestInteger {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int largest = Integer.MIN_VALUE; // initialize largest to the smallest possible integer
        
        while (true) {
            System.out.print("Enter an integer: ");
            int number = scanner.nextInt();
            
            if (number < 0) {
                break; // stop reading input when the user enters a negative integer
            }
            
            if (number > largest) {
                largest = number; // update largest if number is greater
            }
        }
        
        if (largest != Integer.MIN_VALUE) {
            System.out.println("The largest integer is: " + largest);
        } else {
            System.out.println("No positive integers were entered.");
        }
        
        scanner.close();
    }
}

The program uses a while loop to repeatedly read integers from the user. If the user enters a negative integer, the loop is exited. If the number entered by the user is greater than the current value of largest, largest is updated. After the loop exits, the program checks if any positive integers were entered. If so, the largest integer is printed. Otherwise, a message is printed indicating that no positive integers were entered.

You can copy and paste this code into a Java file (e.g., LargestInteger.java) and run it using the javac and java commands.

create a program that reads series of integers from user and output the largest integer. Program should stop reading input when the user enters a negative integer

Sure, here's a Python code that does what you're asking for:

largest = -99999999  # arbitrary small value to compare against
while True:
    num = int(input("Enter an integer: "))
    if num < 0:
        break
    if num > largest:
        largest = num
        
if largest == -99999999:
    print("No positive integers were entered")
else:
    print(f"The largest integer entered was {largest}")

In this code, we first initialize a variable largest with an arbitrary small value (-99999999 in this case). We then enter a while loop that runs indefinitely until we explicitly break out of it using the break statement.

Inside the loop, we prompt the user to enter an integer using the input() function and convert it to an integer using the int() function. We then check if the entered integer is negative; if it is, we break out of the loop. Otherwise, we compare it to the current largest value and update largest if the entered integer is greater.

Finally, we check if any positive integers were entered at all by checking if the value of largest was ever updated from its initial value. If it wasn't, we print a message saying that no positive integers were entered. Otherwise, we print out the value of largest.

I hope this helps! Let me know if you have any further questions.

Sure, I can help you with that. Here's a Python program that does what you're asking for:

largest = None

while True:
    num = int(input("Enter an integer: "))
    if num < 0:
        break
    if largest is None or num > largest:
        largest = num

if largest is not None:
    print("The largest integer entered is:", largest)
else:
    print("No positive integers were entered.")

This program uses a while loop to repeatedly ask the user for integers until they enter a negative integer. It keeps track of the largest integer entered using a variable called largest.

Each time the user enters an integer, the program compares it to the current value of largest. If the integer is greater than largest, it replaces largest with the new integer.

When the user enters a negative integer, the loop ends and the program checks if any positive integers were entered. If so, it prints the largest integer. If not, it prints a message saying that no positive integers were entered.

I hope this helps!
