Question

In java, I should asked the user to enter 10 integers, then display the highest and the lowest integers he entered. How could I do that using a do while loop? Please help.

Answer 1

How to do it is not language dependent. That would be actually coding it, but you should be able to figure that out once you have a plan.

So the real question is how to make a plan. Think about this. You need two outputs, a high and a low. So, declare them! Then, what would you need to do inside the loop to detect if you need to change them?

Answer 2

I know, but I can't get it. I already have my code but It can only display the right lowest number, and it displays the wrong highest number.

Answer 3

Well, how are you deciding if you need to change the high?

Answer 4

I don't know. Could you help?

Answer 5

I mean in your code. What are you doing each time to the numbers that are input?

Answer 6

Here is my code:
//code to ask the user for ten integers
do
{
value = input.nextInt();
for(int x = 1; x <= value; x++)
highest = value;
for(int y = 1; y >= value; y++)
lowest = value;
a++
}
while(a <= 10)
//code to display the result

Answer 7

Why are you using the for loops? Just a simple if statement is all you need there.

Answer 8

See, the for loops can not handle it is I enter a negative integer. If my highest is -1 and my lowest is -3, your code will miss that.

Answer 9

Okay I get it :)) Thanks
