JAVA
Write a program that repeatedly reads in integers until a negative integer is read. The program also keeps track of the largest integer that has been read so far and outputs the largest integer at the end.

Ex: If the input is:
2 77 17 4 -1

the output is:
77
Assume a user will enter at least one non-negative integer.

The program is an illustration of loops

Loops are program statements that are used to execute repeated statements

The program, written in Java where comments are used to explain each line is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

int num;

//Get input from the user

num = input.nextInt();

//Initialize the largest to the first input

int maxn = num;

//This loop is repeated until a negative input is recorded

while (num >=0){

//If the current input is greater than the previous largest

if (num>maxn){

//Set largest to the current input

maxn = num; }

//Get another input from the user

num = input.nextInt();

}

//Print the largest

System.out.print("Largest: "+maxn);

}
