Boa tarde, Pessoal
Estou com um problema para excluir linhas de uma jtable, e por não ter muita experiência estou com dificuldades em resolver a exceção.
Codigo da Tabela:
package ModeloBeans;
import java.util.ArrayList;
import javax.swing.table.AbstractTableModel;
/**
*
-
@author fsantos
*/
public class ModeloTabela extends AbstractTableModel{private ArrayList linhas = null;
private String[] colunas = null;public ModeloTabela(ArrayList lin, String [] col){
setLinhas(lin);
setColunas(col);}public ArrayList getLinhas(){
return linhas;
}
public void setLinhas(ArrayList dados){
linhas = dados;
}
public String[] getColunas(){
return colunas;
}
public void setColunas(String[] nomes){
colunas = nomes;
}
public int getColumnCount(){
return colunas.length;
}
public int getRowCount(){
return linhas.size();
}
public String getColumnName(int numCol){
return colunas[numCol];
}
public Object getValueAt(int numLin, int numCol){
Object[] linha = (Object[]) getLinhas().get(numLin);
return linha[numCol];
}
}
Código para a exclusão:
int linhaSelecionada = jTable_ItensAdd.getSelectedRow();
if (jTable_ItensAdd.getSelectedRow() != -1) {
DefaultTableModel ModeloTabela = (DefaultTableModel) jTable_ItensAdd.getModel();
ModeloTabela.removeRow(jTable_ItensAdd.getSelectedRow());
int quantosRegistros = jTable_ItensAdd.getRowCount();
if (quantosRegistros > linhaSelecionada) {
jTable_ItensAdd.setRowSelectionInterval(linhaSelecionada, linhaSelecionada);
} else if (jTable_ItensAdd.getRowCount() > 0) {
jTable_ItensAdd.setRowSelectionInterval(linhaSelecionada - 1, linhaSelecionada - 1);
}
} else {
JOptionPane.showMessageDialog(null, "Por Gentileza Selecione uma linha");
}
