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

Code: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 calledHelloWorld

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: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
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();
}
}

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
