Question

Anyone can help me with Java programming problems?

Answer 1

You would be better served if you were to simply ask the question you need assistance with.

Answer 2

alright thanks

Answer 3

I do have couple of questions on java I tried to solve them but still giving me an error

Answer 4

as you can see this question: Write a for loop that prints in ascending order all the positive integers less than 200 that are divisible by both 2 and 3, separated by spaces.

I tried everything for this question and now I deleted all my wrong answers!! because I was angry.

Answer 5

int i;
for (i=0;i<200; i++)
{
if(i%2==0 i%3==0)
{
System.out.println [i];
}
}

This is what I had for an answer but still getting error

Answer 6

Try:
```
public class Main{
public static void main(String[] args) {
for (int i = 1; i < 200; i++) {
if ((i % 2) == 0 && (i % 3) == 0) {
System.out.println(i);
}
}
}
}
```

Answer 7

What Opcode is saying is that you're missing a few elements:

The main function (which tells the JVM what to do)
The && operator (logical and, returns true iff both booleans are true) between i % 2 == 0 and i % 3 == 0 (because supposedly you want the number to be divisible by 2 and 3)
Replace [] with () when declaring function arguments.
VALID: System.out.println("")
INVALID: System.out.println[]

Answer 8

daniel wats the difference between & and && in java

Answer 9

The problem is actually a grouping problem. The statement:
if ((i %2) == 0 && (i % 3) == 0) needs additional parenthesis to group the checks together.

if ( ( (i%2) == 0) && ( (i%3) == 0))

This will make the program work.

Answer 10

A single ampersand is a bit-wise and. A double ampersand ands boolean values.

Answer 11

Anyone please help me get started with this problem in java its due tonight.

Answer 12

Make a Java program that prints 3 lines and then uses one Turtle in one World to draw two digits
or letters near the center. Learn to quickly write, save, test and improve programs outside of lab, and
upload course work to Blackboard for credit, so this is not a problem.

Answer 13

1. Code in the main method three calls to method System.out.println( ... ) print on
3 separate lines your full name, your UAlbany NetId and the "iClicker ID" from the back of
your iClicker
The code that prints the ID of one of my iClickers is
System.out.println( "348F05BE" );
2. Under the lines that commanded the printing, code additional lines to make a World, and then
make a Turtle in that World. Here's how:
World wRef = new World( );
Turtle tRef = new Turtle( w );
The two assignments coded by the two = symbols cause two variables wRef and tRef to
hold, as their values, references to two new objects.  wRef is NOT a World; tRef is NOT
a Turtle. wRef is the name of a reference variable; it's ok to say, for short, wRef is a
variable. Similarly, tRef is the variable your program will use to refer to a Turtle for the
purpose of telling it (or he or she) to move forward, turn and put its (his or her) pen up or down.
These points will be stressed soon but not right away. For now, just base your work on my
example.
3. Finish the program to make the Turtle draw, the first above the second, near the middle of
Project 1
Introduction to
Computer Science
ICSI201
Spring 2013the window, the any two different digits or letters of your iClicker ID UNLESS THEY ARE B
or E. If you have a B or an E or both, replace them with other digits or letters from your
iClicker ID.
The only Turtle methods you are allowed to use now are
tRef.forward( integer distance )
tRef.turn( double amount of rotation )
tRef.penUp( )
tRef.penDown( )
and, optionally, setPenColor(... ) and/or setPenWidth( ... ).
The moveTo( ... ) and other methods are ok in FUTURE ASSIGNENTS, but NOT
Project 1, because moveTo makes the problem solving practice you get too easy!
Important: How to figure out solutions to problems like this:
1. Study my sample code and its results: Trace using a pencil what the Turtle does (it
mostly moves in a straight line or turns in place a given number of degrees) in order to draw
the B and the E.
2. Write original code to draw your two digits or letters.
3. Finish, test, perfect and enjoy the first digit or letter BEFORE trying to work on the second.
4. Figure out, code, test, and IMPROVE your artistic results JUST A LITTLE AT A TIME,
running the program and seeing the results again and again. It is OK to use trial, error and
correction, which is what I did.
