Loops??

[srikanth reddy]

class JMM118 {
  public static void main (String[] args) {
    int i = 0, j = 9;
    while (i++ <= j--) {i++; if (j < 5) break;}
    System.out.print(i + "," + j);
}}

please help me with the process...iam getting 8,5...

class JMM119 {
  public static void main (String[] args) {
    int i = 0, j = 9;
    do {
      if (j < 4) {break;} else if (j-- < 7) {continue;}
      i++;
    } while (i++ < 7);
    System.out.print(i + "," + j);
}}

here what happens when break and continue of if statement is executed??

By adding some System.out.printlns and making it prettier.

 
class JMM118 {
  public static void main (String[] args) {
    int i = 0, j = 9;
    while (i++ <= j--) {
i++;
System.out.println("I="+i+" J="+j);
if (j < 5) {
System.out.println("Just about to break. I="+i+" J="+j);
break;
}
}
    System.out.print(i + "," + j);
}}
 
you can see how it is thinking
 
Here are the results
 
I=2 J=8
I=4 J=7
I=6 J=6
I=8 J=5
9,4
 
Press any key to continue . . .
 
 

Hope that helps.

I' never can understand why comd eCODE tags has the text small and some larger.

Running in a different low priority thread to Mark (on paper ) I reckon you just forgot that after the last comparison i++ < j-- jumped out of the loop, i and j had been incremented respectively decremented. That is 8,5 gets you out of the loop but then i is 9 and j is 4. Makes you dizzy eh?

Actually I had problems doing one like this on the real exam - at the same time there were three people trying to get the PC next to me working.

barry i didnt get u ....try to get pc means...

Can we bring pencil and scratch paper to the test? I can do these problems quicker if I can write down what happens in the iterations.

The testing center will provide pencil & paper. Not allowed to bring your own. I had to also check my jacket. Nothing else allowed in (bags, cell phones, etc).
