将while循环转换为每个循环

Question

I'm trying to rewrite this for loop into a for each loop.

 int k = 0;
  while(k < farmArray.length) {
     System.out.println(farmArray[k].getOwner());
     k++;
  }

This is what i've tried

int k = 0;
for(int Farm:farmArray)
{
  System.out.println(farmArray[k].getOwner());
 k += Farm;
}

can anyone point me in the right direction? thanks.

Answer 1

for (Farm farm : farmArray) {
    System.out.println(farm.getOwner());
}

I think you were over-thinking it... :)

Answer 2

Remove your index completely.

for(Farm farm : farmArray) {
    System.out.println(farm.getOwner());
}

Or you can keep track of you index

int k = 0;
for(Farm farm : farmArray) {
    System.out.println("Farm #" + k + " is owned by: " + farm.getOwner());
    k++;
}

But you should use a for loop for this

for(int k = 0; k < farmArray.length; k++) {
    System.out.println("Farm #" + k + " is owned by: " + farmArray[k].getOwner());
}
