A Little Help With Java

i have a little problem with java.

for(i=0;i<=10;i++)
    {
        System.out.println(i);
    }
the output is 0 1 2 3 4 5 6 7 8 9 10
my problem with this is that it begins with 0. Now since i=0 and its less than 10, its supposed to increment it by one so the output should have started with 1.
I could just change the value of i such that i=1; but that would create another issue

   ArrayList<Integer> points;
       points = new ArrayList<Integer>();
       System.out.println(points.size());

   for(i=0;i<=points.size();i++)
       {
        points.add(i);
        System.out.println(i+" The size is "+points.size());
        System.out.println(points.get(i));
        if(i==9)
        {
            System.out.println("Out ok");
            break;
        }
       
       
       }
Now my array would start from 0 which of course i don't want.

if i>1; then would generate an exception


Problem 2: I wrote a program to roll a pair of die and count the number of rolls. The program would end if it gets a 1,1.

public class NewEmptyJavaApp2 {


   public static void main(String args[])
   {
            int x=0;
            int y=0;
            int count = 0;
            int count1 = 0;
            int count2 = 0;

            while(true)
            {
                x=(int)(6*Math.random()+1);
                y=(int)(6*Math.random()+1);
                count++;
                if(x!=1 && y!=1) //Here lies the problem.if changed to || works well
                {    count1++;
                     System.out.println("'"+x+"','"+y+"'");
                }
                else
                {
                    count2++;
                    System.out.println("'"+x+"','"+y+"'");
                    break;
                }
               
            }
            System.out.println("Total:"+count);
            System.out.println("Non snake:"+count1);
            System.out.println("snake:"+count2);
   }
}

The problem here is the && operator. From my understanding && is supposed to evaluate both conditions but in this case if x=1 and y>2 the program would end which is totally incorrect.

Please could someone help me clarify these issues. Thanks.

Thanks for the reply. That solved the problem but still am not quite clear on this issue.
I guess its more studying for me as am ne to java.
Okay for question 1, the problem is that the ouput starts from zero instead of 1
for(i=0;i<10;i++)
{
    System.out.println(i);
}
since i=0 already the first value of i that should be printed is 1 and not 0;  Thanks

Thanks aquastar its just more study for me.

i've not tested this yet
but i think maybe code could be different if u tried this:


for(int i=0;i<10;++i){

System.out.println(i);

}

typing from a public pc tell me if it gives u what u want.

In a loop of this type
for ( exp1; exp2; exp3 )
{
.
//stuff
.
}

exp1 is evaluated, exactly once
exp2 is evaluated is a boolean expression that determines if the loop should continue
exp3 is evaluated every time the loop is iterated.


A && B

like you guessed && has a sort of short circuit effect hence,

if A is true , B would be evaluated
if A is false, B is ignored (this is because false AND anything results in false).
