The code I tried was as follows(PLEASE NOTE since my code is

an example here):
We don't need you whole code but we do need something that compiles and
runs.
String line = {"word 1", "word 2","word 3","word 4"};
You can't assign an array of Strings to a String!
String[] headings = {"word 1", "word 2","word 3","word 4"};
At this point you don't need to split it. Just use it in a JTable
constructor.
System.out.println("Before trying to break " +line);
int pos=0;
while((pos = line.indexOf(" "))>-1){
line = line.substring(0,pos)+line.substring(pos+1);
}
System.out.println("After breakage\n" +line);
String delims=" +"; //(How can i try this - like RGB says with
knowing the embedded spaces. From what I see I have one embedded space
in between Value and 3 like in the
example...
String[] headerLabels=line.split(delims);
for (int i=0;i<headerLabels.length;i++){
System.out.println(headerLabels[i]);
}
Object[][] data={{}};
model=new DefaultTableModel(data,headerLabels);
table=new JTable(model);
Any ideas guys?
1)
String#split()

But I don't like the value with which you initialize "line".
