Using an if statement with an array

nfeldbaum

Hello,

I'm rather new to coding, and I'm having a few problems with some of my code. I have an array called array1 that has many empty parts. So I used the sort() method to put those first in the array so that I could make a for loop that found the last index where array1[i] was empty. This is what I wrote:

for (int i = 0; i < array1.length; i++);
{
  if (array1[i].equals(""))
  {
    lastBlank = i;
  }
}

The program keeps telling me that it "cannot find anything named 'i,' though. Any ideas about what I'm doing wrong?

You should aim to post a running code! [-X

_vk

the ; in line one... It is "closing" the block, so i is out of scope when you try to read it. Just remove this entry

here like _vk said

String [] array1 = { 
  "s", "e", "q", "", "ws", "dd"
};

int lastBlank=0;

for (int i = 0; i < array1.length; i++)
{
  if (array1[i].equals(""))
  {
    lastBlank = i;
  }
}

print (lastBlank);
print (" in ");
for (int i = 0; i < array1.length; i++)
  print (" >" + array1 [i] + "<, ");

Thank you all so much. Just a stupid typo!
