Question

Help please.

Answer 1

import java.util.Random;
class Three1
{
public static void main(String[]args)
{
Random random = new Random();
float x = random.nextFloat();
System.out.println("x = " +x);
float y = random.nextFloat();
System.out.println("y = " +y);
float min = (x<y? x:y);//Label 01
float max = (x<y? x:y);//Label 02
System.out.println("Minimum = " + min);
System.out.println("Maximum = " + max);
}
}

Answer 2

Modify the above program by replacing the lines commented as Label 01 and Label 02 with the normal if statements. How do you do that?

Answer 3

Do you understand if statements currently?

Answer 4

ya I mean I knw hw to use that in C++ bt dnt knw to do in java

Answer 5

They work the same way in Java.

Answer 6

Bt when I included 1 in the abov program I didnt get t right.

Answer 7

These are the two statements in question, as I'm sure you can see they're conditional statements.
float min = (x<y? x:y);//Label 01
float max = (x<y? x:y);//Label 02
Based on the help you offered on another question I can see you understand the if/else so what is the error you are getting?

Answer 8

This is how I changed it.
if(x<y? x:y)
{
System.out.println("Minimum = " + min);
}
I dnt knw if this is right. I am new to Java.

Answer 9

Well you are not making an assignment to 'min' in that sample code but other than that, yes.

Answer 10

Sorry. I didnt get u.

Answer 11

That help I offered was my maiden attempt after learning if statements. I even dnt knw vat the coding I hav written is right.

Answer 12

The last bit of code you put up says, if, x is greater than y, is true, x but if false y. Then you step in and print a min to the screen. I was just pointing out that you had not made an assignment.

Answer 13

*dat

Answer 14

Okay, then let's examine the statement you're given. float min = (x<y?x:y);
This says that if (x less than y is true) assign x to min, otherwise assign y to min.
How would you turn that into an if/else statement?

Answer 15

if(x<y)
{
System.out.println("Minimum is " +x);
}
else
{
System.out.println("Minimum is " +y);
}

Answer 16

Is that right?

Answer 17

Yes, I would only add an assignment before the print statement if you wanted to save those values.

Answer 18

u mean x = some value and y = some value. Is that so?

Answer 19

Let's assume min and max are declared at the top of main like this:
float min, max;
I'm suggesting you code the if/else with this additional statement.
if(x<y)
{
min = x;
max = y;
System.out.println("Minimum is " +x);
}
else
{
min = y;
max = x;
System.out.println("Minimum is " +y);
}

Answer 20

If you do not care to save those values then your solution is 100% correct.

Answer 21

I understand it nw. I really didnt understand vat those commented statements meant earlier. Only after u told me the meaning I got that idea. Nw it's clear. Thank you soooooooo much.

Answer 22

:) You're welcome.
