Question

I have a simple java statement along the lines of:

    String[] ykl = yklList.get(0).split(" ");  

where, yklList is an ArrayList containing sentences which are split into words. The above works fine.

When I now try and loop this:

Loop:1
for (int i=0;i<=4;i++)
{
  String[] ykl = yklList.get(i).split(" ");
}

It does not seem to work and throws me a compile error. Is the above loop wrong?

I have another for loop after the above:

Loop:2
for (String ykl : yklList)
{
//do something
}

It throws me a compile error here saying:

cannot find symbol
symbol  : variable ykl
location: class test
for (String ykl : yklList) 

Presumably Loop 1 went wrong somewhere?

Edit:

The “full” code looks something like this:

for (int i=0;i<=yklList.size()-1;i++)
{
String[] ykl = yklList.get(i).split(" ");  

}       
for (String y : ykl)  
{  
t.add(y);  
}   

and the error is:

cannot find symbol
symbol  : variable ykl
location: class test
for (String y : ykl)

Regarding to your update:

You define ykl in the first loop. So the variable is not in the scope of the second loop. Your code have to look like this:

for (String yklSentence : yklList) {
   String[] ykl = yklSentence.split(" ");  
   for (String y : ykl) {  
     t.add(y);  
   } 
}

By the way: If you would use an IDE like Eclipse you would see those errors in the editor!
