my code permit to put list content in jtable by using the method "save1" which is used in a jbutton. The problem is that there are some exception after running. This line of instructions "DefaultTableModel tableModel = fen.getmodel();" in the method save1 is the reason of the exception.
Here is the codes of "save1", the button and the exceptions:
public void save1(String pathToExplore) throws IOException, JDOMException{
ArrayList<String>liste= getArrowTexts();
System.out.println(liste);
Lister_path diskFileExplorer = new Lister_path(pathToExplore,true);
ArrayList<String> result= diskFileExplorer.Lister_path();
Lister_Rep listerep=new Lister_Rep(pathToExplore,true);
ArrayList<String> result1= listerep.Lister_Rep();
int l=0,row=0,i=0;
//Fenetre1 fen=new Fenetre1();
DefaultTableModel tableModel = fen.getmodel();
while(i< result.size()&& l<result1.size()){
String nompath=result.get(i);
ReadExeLS reedexel=new ReadExeLS();
ArrayList<String> lisn=reedexel.ReadEx(nompath);
int j=0,k=0;int S=0;
while(j<liste.size()&&k<lisn.size()){
if((liste.get(j)).equals(lisn.get(k))){
System.out.println(liste.get(j));
j++;k++;S++;
System.out.println(S);
if(j==liste.size()){
k=lisn.size();}
else{ k++;}
}else{k++;
System.out.println(S);}
}
if(S==0){
System.out.println(result1.get(l));
tableModel.addRow(new String[] {"Not case","Success","Failed"});
tableModel.setValueAt(result1.get(l), row, 2);
l++;row++;i++;
}else if(S==liste.size()){
System.out.println(result1.get(l));
tableModel.addRow(new String[] {"Not case","Success","Failed"});
tableModel.setValueAt(result1.get(l), row, 1);
l++;row++;i++;}
else{
tableModel.addRow(new String[] {"Not case","Success","Failed"});
tableModel.setValueAt(result1.get(l), row, 0);
System.out.println(result1.get(l));
l++;row++;i++;
}
}
}
