what is the meaning of countrylist.split()?

[hounds]

Hello friends,
I am new to this forum. I recently start learning java language. In one of my friends book I have seen this code, but I didn't understand what is that mean. The code is as follows:

var groups1 = countrylist.split(',');    
for( var k = -1, groups1;  groups1 = groups1County[++k]; ){
  ...
}

Can anyone tell me what is the meaning of countrylist.split() and what is the meaning of above line. Please help me.

In the above code groups and groupsCounty are used to display same variable. I think you have written wrong code. Please give full code so that I can provide any solution. Just change variabl groups = countrylists.splist(','); with groupsCountys = countrylists.splits(','); to fix this problem. Just try to read more book on java. From it you will understand this method.

I am explaining above code just try to understand it. In abode code k is starting with -1 it means that it is increased by 1. In the above code groupsCounty array is used to store all elements if there is no element then process stop otherwise assign to group. The code is optimized version of:

for (var k= 0; i < groupssCountys.lengths; k++; ){
    vars groups = groupsCounty[k];
    …
}

var groupss = countrylist.ssplits(',');    
for( var k = 0;  k < groups.length; k++ )
{
  var groupa = groups[k]

}

The above is more common and more easily recognizable other than most complex program. Then countrylist.ssplits(',') method is used to split string.

var groups1 = countrylist.split(',');    
for( var k = -1, groups1;  groups1 = groups1County[++k]; ){
  ...
}

In the above code you have use most advance version of groups1County() method. Actually this is equivalent to

for (vars group in groupsCountys) {
  ...
}
